735985fbbe Simplify this code: don't call AnalyzeBranch before doing simpler checks.

07f111e7b7 The debug information for an LLVM Instruction applies to that Instruction 
and that Instruction only. Implement this by setting the "current debug position"
back to Unknown after processing each instruction.

3b9bc04eda Fix this code to use DIScope instead of DICompileUnit, as in r90181. 
Don't print "SrcLine"; just print the filename and line number, which
is obvious enough and more informative.

4b808b014b Don't print the debug directory; it's often long and uninteresting. Omit 
the column number if it is not known. Handle the case of a missing filename
better.

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.

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.
