as many tests as possible.

Changed my mind. We now allow remat of instructions whose defs have subreg indices.

Let callers decide the sub-register index on the def operand of rematerialized instructions.
...
Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.

Split the Add, Sub, and Mul instruction opcodes into separate
...
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.
For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.
This implements the first step of the plan outlined here:

Re-apply 55467 with fix. If copy is being replaced by remat'ed def, transfer the implicit defs onto the remat'ed instruction.

If a copy isn't coalesced, but its src is defined by trivial computation. Re-materialize the src to replace the copy.
