94da9193a6 ("grep: add support for PCRE v2", 2017-06-01) allocate
a stack and assign it to a match context, but never pass it to
pcre2_jit_match, using instead the default.

This might have positive performance consequences (per the comments)
but haven't tested them; if there is no difference might be better
instead to remove the stack and match_context and save the related
memory, since it seems the default was working fine anyway.
