f9a432a613 Cleanup some from my DomSet-removal changes. Add a new 
isReachableFromEntry
test to ETForest to factor a common test out of code.

bcb7b5ca5d Implement more feedback: 
* Allow attributes to be added and removed singly or jointly so that in
  the future something like -pruneh can manipulate them more easily.
* Move functions generally only useful for LLVM internals to the end of
  the accessors list instead of the beginning.

7cf9d12f2e Add DomSet back, and revert the changes to LoopSimplify. Apparently the 
ETForest updating mechanisms don't work as I thought they did.  These changes
will be reapplied once the issue is worked out.

0160bf7114 rearchitect the registration mechanism used by the command line option stuff. 
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called.  In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.

d0cc2333d1 Switch some vectors to smallvectors. This reduces amount of malloc'd 
memory that occurs before main starts from 5104 to 4864 bytes with a dummy
example app.

d39ae2fa6d Add a helper class (APSInt) which can represent an APInt along with sign 
information.  This is useful when a value does have a sign associated with
it.  This shouldn't be used generally in LLVM for mid-level optimizer stuff.

functions, saving significant space and time.

419396d2fe For PR1297: 
Implement bswap, ctpop, ctlz, and cttz utilizing the new overloaded
intrinsic feature of tblgen. By defining llvm_int_ty to have an ValueType
of iAny, any intrinsic using that type becomes an overloaded intrinsic.
This signals that a) any integer type could be used for that argument and
b) the intrinsic needs a suffix to match each such argument for the
actual intrinsic.

5ac41f7bc9 For PR1297: 
Intrinsic functions might need to be generated (if they are overloaded) so
returning a const char* is no longer possible. Change getOperationName to
return a std::string instead.

e1b0aae7c7 For PR1297: 
Change the interface to the getName, getType, getDeclaration methods to
include the "actual" types of the result/arguments. This is necessary to
support overloaded intrinsics.

f4ea8f8a73 For PR1297:

bit width. This is used for intrinsics overloading on integer type.
