MIPS: Remove the forward-bailout stack from the non-optimizing compiler.

Port r9863 (0996dc77)

Original commit message:
This was pretty heavyweight.  It was kept in just for a few corner cases
that assumed it was there.  We can work around them by making sure that the
expression in a reified test context is always really the expression that
was visited in that context; and by inspecting the context manually and
consing up a pair of extra AST IDs for the unusual case of unary not in a
value AST context.
