Duncan Sands e9da6db67f Convert a bunch of uses of 'bytecode' into 'bitcode'. This 
is not everything, but the remaining cases are less trivial.

Jim Grosbach 0860520527 Add specializations of addrmode2 that allow differentiating those forms 
which require the use of the shifter-operand. This will be used to split
the ldr/str instructions such that those versions needing the shifter operand
can get a different scheduling itenerary, as in some cases, the use of the
shifter can cause different scheduling than the simpler forms.

Bob Wilson 97bf273870 Increase ARM APCS preferred alignment for i64 and f64 from 32 bits to 64 bits. 
LDM/STM instructions can run one cycle faster on some ARM processors if the
memory address is 64-bit aligned.  Radar 8489376.

Daniel Dunbar a9dd1998cc lit: Fix a subtle resource usage bug when executing tests using the internal 
shell runner.

We would inadvertently end up holding on to handles to the temporary files
longer than we should have been. On Win32, where open handles lock some file
operations, this caused problems in tests which would try to move temporary
files around (as Clang does by default now).

Many thanks to Francois Pichet for the excellent detective work on this.

Chris Lattner f60062fd55 add basic avx support to the disassembler, also teach it about ssmem/sdmem 
operands.

With this done, we can remove the _Int suffixes from the round instructions
without the disassembler blowing up.  This allows the assembler to support
them, implementing rdar://8456376 - llvm-mc rejects 'roundss'

Chris Lattner ff3a3930a0 add asmparser support for cvttpd2dq by removing some Int_ prefixes.

Chris Lattner a63292a3ca implement rdar://8456378 and PR7557 - support for the fstsw, 
an instruction that requires a WHOLE NEW wonderful kind of alias.

Chris Lattner b44fd24fc1 change the protocol TargetAsmPArser::MatchInstruction method to take an 
MCStreamer to emit into instead of an MCInst to fill in.  This allows the
matcher extra flexibility and is more convenient.

Eric Christopher 3a7e8cd6bd Rework comparison handling to set a register on true/false. This avoids

Bill Wendling d848beb1e5 Fix a FIXME. _foo.eh symbols are currently always exported so that the linker 
knows about them. This is not necessary on 10.6 and later.

Dan Gohman 25a7bc9081 When an MDNode changes to become identical to another MDNode, 
delete the MDNode that changed, rather than the other MDNode.
This is less work, because it doesn't require the changed node
to be re-inserted into the uniquing map and it doesn't require
the is-function-local flag to be recomputed. Also, it avoids
trouble when the existing node is part of a complicated
data structure.

Owen Anderson a3181e2d79 Add a subtarget hook for reporting the misprediction penalty. Use this to provide more precise 
cost modeling for if-conversion.  Now if only we had a way to estimate the misprediction probability.

Adjsut CodeGen/ARM/ifcvt10.ll.  The pipeline on Cortex-A8 is long enough that it is still profitable
to predicate an ldm, but the shorter pipeline on Cortex-A9 makes it unprofitable.
