(perl #125351) abort parsing if parse errors happen in a sub lex

We've had a few reports of segmentation faults and other misbehaviour
when sub-parsing, such as within interpolated expressions, fails.

This change aborts compilation if anything complex enough to not be
parsed by the lexer is compiled in a sub-parse *and* an error
occurs within the sub-parse.

An earlier version of this patch failed on simpler expressions,
which caused many test failures, which this version doesn't (which may
just mean we need more tests...)
