9008ca6b6b 2nd attempt, fixing SSE4.1 issues and implementing feedback from duncan.
PR2957

ISD::VECTOR_SHUFFLE now stores an array of integers representing the shuffle
mask internal to the node, rather than taking a BUILD_VECTOR of ConstantSDNodes
as the shuffle mask.  A value of -1 represents UNDEF.

In addition to eliminating the creation of illegal BUILD_VECTORS just to 
represent shuffle masks, we are better about canonicalizing the shuffle mask,
resulting in substantially better code for some classes of shuffles.

4af325d1b4 Rename GR8_ABCD to GR8_ABCD_L and create GR8_ABCD_H, and use these

initial patch!

Also, make getStoreRegOpcode and getLoadRegOpcode aware of the
needs of h registers.

e2bcf13be5 Under unusual circumstances (jitting a function that causes the creation of
another stub, but then never calling the jitted function) can cause the JIT to
leave a stub in place. Judging by the comments this is a known deficiency, so
we're just not going to use AssertingVH for the StubToFunctionTy map.

Also shorten some lines longer than 80 columns.

This fixes the "make check" failure with ocaml on x86-64 linux.

a2165ed6ee Allow aliasee to be a GEP or bitcast instead of just a bitcast.
The real fix for this whole mess is to require the operand of the
alias to be a *GlobalValue* (not a general constant, including 
constant exprs) but allow the operand and the alias type to be
unrelated.

This fixes PR4066

4cdc44c82c Fix g++-4.4.0 warning, it was causing llvm-nm to fail on wrapped BC files:
Path.cpp:59: warning: case label value exceeds maximum value for type
magic[0] is a (signed) char, but some case values are unsigned (e.g. 0xde).
When magic[0] was 0xde, the switch has taken the default branch instead of case
0xde branch.
Apparently this was the behaviour with older versions of gcc too, but not with g++.
Now g++-4.4 behaves as gcc, and ignores unsigned case values out of range signed
range.

0adb527d16 Do not share a single unknown val# for all the live ranges merged into a physical sub-register live interval. When coalescer is merging in clobbered virtaul register live interval into a physical register live interval, give each virtual register val# a separate val# in the physical register live interval. Otherwise, the coalescer would have lost track of the definitions information it needs to make correct coalescing decisions.
