Dan Gohman 4c3034f711 Simplify this code a little. In the fast scheduler, CreateNewSUnit 
and CreateClone don't add any extra value.

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.

Dan Gohman f4d95fdce9 Move the code for printing a graph node label for an SUnit into 
a virtual method of SelectionDAG.

dump in terms of it.

Devang Patel 79303b2572 Do not use separate utility to walk all instructions and remove dead dbg intrinsics. Let instcombiner do this job.

Devang Patel 827bced2b1 Let instcombiner remove redundant dbg intrinsics.

Devang Patel 7ed6c5317c If there are two consecutive llvm.dbg.stoppoint calls then 
it is likely that the optimizer deleted code in between these
two intrinsics. Keep only the last llvm.dbg.stoppoint in this case.

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.

Dan Gohman 7f480e04eb Revert r59640. It broke this test for builds that aren't 
configured with llvm-gcc.

Dan Gohman f09aabfe70 Use %llvmgcc -xassembler instead of invoking as directly. This avoids 
problems for example when LLVM is built with --with-extra-options=-m64
and as defaults to x86-32 mode.

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.

Daniel Dunbar 2dd5aa4f11 LLVMC2: Teach llvm_gcc_c tool about -include and -fsyntax-only. 
- Only focusing on llvm_gcc_c for now, eventually this needs to be
   refactored so it can be shared via all the gcc-like tools.

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.

Duncan Sands 3ca78c675e Remove integer promotion support for FP_EXTEND 
and FP_ROUND.  Not sure what these were doing
here - probably they were sometimes (wrongly)
created with integer operands somewhere that
has since been fixed.
