011f91b5b2 Teach GlobalLoadUsesSimpleEnoughForHeapSRA and the SROA rewriter how to handle 
a limited form of PHI nodes.  This finally fixes PR1639, speeding 179.art up
from 7.84s to 3.13s on PPC.

e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.

2341c22ec7 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.

cddc9dfe97 Implement review feedback for the ConstantBool->ConstantInt merge. Chris 
recommended that getBoolValue be replaced with getZExtValue and that
get(bool) be replaced by get(const Type*, uint64_t). This implements
those changes.

c635f47d9a For PR950: 
This patch replaces signed integer types with signless ones:
1. [US]Byte -> Int8
2. [U]Short -> Int16
3. [U]Int   -> Int32
4. [U]Long  -> Int64.
5. Removal of isSigned, isUnsigned, getSignedVersion, getUnsignedVersion
   and other methods related to signedness. In a few places this warranted
   identifying the signedness information from other sources.

6c38f0bb07 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.
