before it determines which callee-save registers are to be spilled. This allows
the target to make changes such as forcing certain physical registers to be
spilled.

AggregateString += "\0\0";

Doesn't add two nuls to the AggregateString (for obvious reasons), which
broke the asmprinter when the first character of an asm string was not
literal text.

instructions once). We create a map out of them. Then it's no problem to
use the information in it during elimination...
