A utility to run an arbitrary program on each of the LLVM source files.
...
This is like llvmgrep but instead of running grep, it runs the command
given by the first argument. For example, to find the top ten files with
the most lines in llvm, you could:
utils/llvmdo wc -l | sort -nb | tail
Or, to find any source files with the wrong permissions, you could:
utils/llvmdo ls -l | grep -v rw-r--r--
Hopefully, you get the idea.

ADDI can take several forms, including:
...
addi r1, r2, 0
addi r1, <frame index #n>, 0
so we must check for the second parameter being a register for this instruction
to be considered a reg-to-reg copy.

Fix a serious bug in the double constant reader. In particular, because

* Substantially simplify how free instructions are handled (potentially fixing
...
a bug in DSE).
* Delete dead operand uses iteratively instead of recursively, using a
SetVector.
* Defer deletion of dead operand uses until the end of processing, which means
we don't have to bother with updating the AliasSetTracker. This speeds up
DSE substantially.
