6b74e505be Also attempt trivial coalescing for live intervals that end in a copy.
The coalescer is supposed to clean these up, but when setting up parameters
for a function call, there may be copies to physregs. If the defining
instruction has been LICM'ed far away, the coalescer won't touch it.

The register allocation hint does not always work - when the register
allocator is backtracking, it clears the hints.

This patch takes care of a few more cases that r90163 missed.

2e65c29ac6 - If the reaching definition is an undef and the use is a PHI, add the implicit_def to the end of the source block.
- When reaching value is replaced with another, update the cache as well.

9993b88f06 Fix ExpandShiftWithUnknownAmountBit, which was completely bogus.
Pointed out by Javier Martinez (who also provided a patch).  Since
this logic is not used on (for example) x86, I guess nobody noticed.
Tested by generating SHL, SRL, SRA on various choices of i64 for all
possible shift amounts, and comparing with gcc.  Since I did this on
x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit.
What I'm saying here is that I don't have a testcase I can add to the
repository.

dd5eb02304 This initial code is meant to convert TargetData to use an AbstractTypesUser so
that it doesn't have dangling pointers when abstract types are resolved. This
modifies it somewhat to address comments: making the "StructLayoutMap" an
anonymous structure, calling "removeAbstractTypeUser" when appropriate, and
adding asserts where helpful.
