af0921c568 For PR950: 
Implement signless integer types and FunctionType parameter attributes.

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.

5c1e9c39ef Cleanup ConstantFoldCompareInstruction: 
1. Make the arguments const like the other ConstantFold* functions.
2. Clean up evaluateFCmpRelation so it makes sense for floating point.
3. Implement the use of evaluateFCmpRelation to fold floating point CEs
4. Shorten a variable name so more things fit on one line.
5. Fix various comments.

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.

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.

s/ModulePassManager/MPPassManager/g
s/FunctionPassManagerImpl_New/FunctionPassManagerImpl/g
s/PassManagerImpl_New/PassManagerImpl/g

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.

9ac4a6b7d0 Remove the last use of getUnsignedVersion and getSignedVersion from VMCore. 
ConstantInt doesn't care about the sign of the type it represents. It only
cares about the bitwidth so there is no need to make the sign of the type
match the SExt or ZExt constant expression.

d414793dbc For PR950: 
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

a better encoding of the targets data layout, rather than trying to guess it
from the endianness and pointersize like before.

being destroyed at inconvenient times.  Switch to using non-local ManagedStatic
objects, which actually also speeds up ConstRules::get.
