This fixes Mantis bug #512, whose symptom is a compiler abort in some very specific circumstances. The regression test for the bug below documents the long causal chain needed to tickle this abort. compiler/simplify_goal_conj.m: When deleting unreachable code, set the requanify flag, which also causes instmap_deltas to be recomputed. The immediate cause of the bug was an instmap_delta that should have been thus recomputed, but wasn't. Do this in both places where simplification can delete dead code, though the Mantis 512 test case involves only one. tests/valid/bug512.m: A regression test for this bug. tests/valid/Mercury.options: tests/valid/Mmakefile: Enable the new test case, and run it with the flags that tickle the bug it is guarding against.
