Scott Michel a7521ee3df CellSPU: Custom lower truncating stores of i8 to i1 (should not have been 
promote), fix signed conversion of indexed offsets.

Dan Gohman 60cb69e665 Experimental post-pass scheduling support. Post-pass scheduling 
is currently off by default, and can be enabled with
-disable-post-RA-scheduler=false.

This doesn't have a significant impact on most code yet because it doesn't
yet do anything to address anti-dependencies and it doesn't attempt to
disambiguate memory references. Also, several popular targets
don't have pipeline descriptions yet.

The majority of the changes here are splitting the SelectionDAG-specific
code out of ScheduleDAG, so that ScheduleDAG can be moved to
libLLVMCodeGen.a. The interface between ScheduleDAG-using code and
the rest of the scheduling code is somewhat rough and will evolve.

Scott Michel ef5e6934cb CellSPU: Do not custom lower i1 stores, rely on type legalization to do the 
right thing and promote the store to i8.

Stuart Hastings 0daa1b4a94 <rdar://problem/6351057> 
Discourage (allocate last) use of x86_64 R12 and R13 due to their
longer instruction encodings.

Sanjiv Gupta 2ae21ee517 Added a more function PIC16 backend. However to get this working a patch in 
ExpandIntegerOperand (LegalizeIntegerTypes.cpp) is needed which is yet to be reworked and submitted.

Dan Gohman c8d2b0135a Don't set neverHasSideEffects on x86's divide instructions, since 
they trap on divide-by-zero, and this side effect is otherwise
unmodeled.

Dale Johannesen aae3a4f864 Move some former testcases (low-probability codegen 
optimizations) into this wishlist.

Oscar Fuentes ba4eb2a9db Adds extern "C" ints to the .cpp files that use RegisterTarget, as 
well as 2 files that use "Registrator"s. These are to be used by the
MSVC builds, as the Win32 linker does not include libs that are
otherwise unreferenced, even if global constructors in the lib have
side-effects.

Patch by Scott Graham!

Dan Gohman 88ba5f0b96 Move the code that inserts X87 FP_REG_KILL instructions from a 
special-purpose hook to a new pass. Also, add check to see if any
x87 virtual registers are used, to avoid doing any work in the
common case that no x87 code is needed.
