Jim Grosbach b22ef71d46 On Darwin ARM, memory needs special handling to do JIT. This patch expands 
this handling to work properly for modifying stub functions, relocations
back to entry points after JIT compilation, etc..

Jim Grosbach 332ad5e016 Indexing off by one resulted in errant encoding of source register for 
reg->reg moves.

Jim Grosbach af929abc01 NeedStub/DoesntNeedStub logic was reversed, leading to not using a stub 
for global relocations that do need them (libc calls, for example).

Duncan Sands 6e42742d2d The result of getSetCCResultType (eg: i32) may be larger 
than the type an i1 is promoted to (eg: i8).  Account
for this.  Noticed by Tilmann Scheller on CellSPU; he
will hopefully take care of fixing this in LegalizeDAG
and adding a testcase!

Dan Gohman 4e072a75cc Implement fast-isel support for zero-extending from i1. 
It turns out that this is a fairly common operation,
and it's easy enough to handle.

Dan Gohman b01a9c94d4 Fix X86FastISel to handle dynamic allocas that have avoided 
getting inserted into the ValueMap. This avoids infinite
recursion in some rare cases.

Jim Grosbach 009db89513 Add support for Canadian Cross builds where the host executables are not 
runnable on the build machine.

There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.

Thanks to Eric C. and Devang P. for pre-commit review.

Dan Gohman 1ab1d31f7a Optimize conditional branches in X86FastISel. This replaces 
sequences like this:
       sete    %al
       testb   %al, %al
       jne     LBB11_1
with this:
       je      LBB11_1

Dan Gohman a78bae34a5 Add a new MachineBasicBlock utility function, isLayoutSuccessor, that 
can be used when deciding if a block can transfer control to another
via a fall-through instead of a branch.

Mikhail Glushenkov f40296bb49 Build system tweaks to make it more convenient for the plugin authors. 
Plugins can be now compiled in with a slight Makefile change.
For example, to compile the new Clang driver, use:

cd $LLVMC2_DIR
make TOOLNAME=ccc2 BUILTIN_PLUGINS=Clang

Owen Anderson c5b45fec6b Use a multimap rather than a map for holding the list of copies to insert, so we don't lose copies when two of them have 
the same source.  I don't know what I was thinking when I wrote this originally.
Note: There's probably a more efficient way to do this, but I need to think about it some more, and about what determinism
guarantees need to be present.

Dan Gohman 88536398ff Fix a think-o in isSafeToMove. This fixes it from thinking that 
volatile memory references are safe to move.

Dan Gohman b158fd751c Work around an interaction between fast-isel and regalloc=local. The 
local register allocator's physreg liveness doesn't recognize subregs,
so it doesn't know that defs of %ecx that are immediately followed by
uses of %cl aren't dead. This comes up due to the way fast-isel emits
shift instructions.

This is a temporary workaround. Arguably, local regalloc should
handle subreg references correctly. On the other hand, perhaps
fast-isel should use INSERT_SUBREG instead of just assigning to the
most convenient super-register of %cl when lowering shifts.

This fixes MultiSource/Benchmarks/MallocBench/espresso,
MultiSource/Applications/hexxagon, and others, under -fast.

Bill Wendling b04e6edba9 "The original bug was a complaint that _mm_srli_si128 mis-compiled when passed 
a constant vector ("{0x123, 0x456}" syntax).  The fix is to simplify the
_mm_srli_si128 macro, and  move the "* 8" from the macro into the compiler
back-end.  I can't change the existing __builtins because so many people are
using them :-(."

Dan Gohman 6388dde98e Split x86's ADJCALLSTACK instructions into 32-bit and 64-bit forms. 
This allows the 64-bit forms to use+def RSP instead of ESP. This
doesn't fix any real bugs today, but it is more precise and it
makes the debug dumps on x86-64 look more consistent.

Also, add some comments describing the CALL instructions' physreg
operand uses and defs.

Duncan Sands d65a4daeea Factorize code: remove variants of "strip off 
pointer bitcasts and GEP's", and centralize the
logic in Value::getUnderlyingObject.  The
difference with stripPointerCasts is that
stripPointerCasts only strips GEPs if all
indices are zero, while getUnderlyingObject
strips GEPs no matter what the indices are.
