1. Always use % for local and @ for global.
2. Replace NameNeedsQuotes with QuoteNameIfNeeded so that any adjustments

3. Implement generation of hex escapes so we don't get "wonky" characters
   in the output.

db7de8e497 merge several fields in GlobalValue to use the same word, move CallingConv
field into SubclassData in Value.  This shrinks GlobalVAlue from 48->40
bytes, Function from 88->76, and GlobalVariable from 76->68.  This trims
4640 bytes off my testcase, reading a bc file without materializing any
functions.

cc56e116fe The (negative) offset from a SymbolTableListTraits-using ilist to its container
object is always constant.  As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits.  This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

71a21677f4 Refactor SymbolTableListTraits to only have a single pointer in it, instead
of two.  This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60).  On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.

591bfa1e0b Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

611d5e2eda Propagate changes from my local tree. This patch includes:
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.

373d2bccea For PR1064:
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

4f14887126 Change the syntax for parameter attributes:
1. The @ sign is no longer necessary.
2. We now support "function attributes" as parameter attribute 0.
3. Instead of locating the return type attributes after the type of a
   function result, they are now located after the function header's
   closing paranthesis and before any alignment or section options.
4. The way has been prepared for a new "noreturn" function attribute but
   there is no support for recognizing it in the lexer nor doing anything
   with it if it does get set.
5. The FunctionType::getParamAttrsText method now has support for
   returning multiple attributes. This required a change in its interface.

I'm unhappy that this change leads to 6 new shift/reduce conflicts, but
in each case bison's decision to choose the shift is correct so there
shouldn't be any damage from these conflicts.

38002bb037 For PR950:
Remove all grammar conflicts from assembly parsing.  This change involves:
1. Making the "type" keyword not a primitive type (removes several
   reduce/reduce conflicts)
2. Being more specific about which linkage types are allowed for functions
   and global variables. In particular "appending" can no longer be
   specified for a function. A differentiation was made between the various
   internal and external linkage types.
3. Introduced the "define" keyword which is now required when defining a
   function. This disambiguates several cases where a named function return
   type could get confused with the definition of a new type. Using the
   keyword eliminates all shift/reduce conflicts and the remaining
   reduce/reduce conflicts.

These changes are necessary to implement the function parameter attributes
that will be introduced soon. Adding the function parameter attributes in
the presence of the shift/reduce and reduce/reduce conflicts led to severe
ambiguities that caused the parser to report syntax errors that needed to
be resolved. This patch resolves them.

b4701a315f At the beginning of run, initialize analyis info availability for _ALL_
pass managers. Otherwise, stale available analysis info, from the managers not
yet run, may cause pass manager to take wrong turn.

This fixes CBE test failures reported by nightly tester.

812cc9c807 Now that ConstantInt::isValueValidForType can handle signed and unsigned
values regardless of the signedness of the constant's type, it is okay to
always make the AsmWriter.cpp print constant ints as signed values. The
AsmParser will automatically handle things like: uint -1 as a result.

Introduce FPPassManager to manage function passes and
BBPassManagers.

Now FunctionPassManagerImpl is an implementation class
used by externally visible FunctionPassManager to manage
FPPassManagers.

Module pass manager (MPPassManager) now manages FPPassManagers
and ModulePasses.

77b7f03711 Rewrite ConstantFoldCastInstruction so that it doesn't use any of the
ConstRules. Remove the casting rules from ConstRules and subclasses. This
cleans up ConstantFolding significantly. Passes all tests.

e9d6e54b36 Make ConstantInt not care about sign any more. To ensure the AsmParser can
still check the validity of signed values an overload to isValueValidForType
was added to allow passing in an int64_t to check.
