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.

2f91f30b93 Fix PR 4057, a crash doing float->char const folding.

at compile time, which seems better.

4d59e1d666 Fix up some problems with getCopyToReg and getCopyFromReg nodes being
chained and "flagged" together.  I also made a few changes to handle the
chain and flag values more consistently.  I found these problems by
inspection so I'm not aware of anything that breaks because of them
(thus no testcase).

f3b0aac190 "I got annoyed at the compiler warnings from ConstantInt::get(Ty, -1,
true), and casts make me nervous and are verbose anyway, so here's a
ConstantInt::getSigned(Ty, int64_t) method. Just overloading
ConstantInt::get() to take an int64_t too would cause ambiguous
overload errors."

b706d29f9c 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.

A clean up of x86 shuffle code, and some canonicalizing in DAGCombiner is next.
