compiler: rewrite t-regs through defining instruction.
* stdlib/optimize.tl (subst-preserve): Rename list param
to insn for clarity.
(careful-subst-preserve): New function. This is like
subst-preserve, but used only for instructions that
have destination registers. It performs a rewrite
such that those destination positions are avoided.
(basic-blocks rename): When the instruction has src
or dst as a target, don't just stop before that
insn. Do the substitution in the source operands using
careful-subst-preserve.
