compiler: bug: unmatchable pattern in optimizer.
This was uncovered by unused variable warnings.
* stdlib/optimize.tl (basic-blocks peephole-block):
The pattern trying to detect wasteful register moves
is incorrect; the reg1 term is intended to be the
@reg1 variable. It is matched literally and so will
not match because the symbol reg1 does not literally
occur in the VM code.
