a49386d8e7 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..

e398f553b2 NeedStub/DoesntNeedStub logic was reversed, leading to not using a stub 
for global relocations that do need them (libc calls, for example).

00b25fea88 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!

659f1ab77f 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.

1c171e1d1c 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.

bba3fb6d18 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.

1c97db4090 "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 :-(."

4aacc3ab83 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.

88d8323743 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.
