Julian Seward 6610ca19b3 Remove existing non-working support for self-modifying code, and instead ...

add a simple compromise, in which the client can notify valgrind
that certain code address ranges are invalid and should be retranslated.
This is done using the VALGRIND_DISCARD_TRANSLATIONS macro in valgrind.h.

At the same time take the opportunity to close the potentially fatal
loophole that translations for executable segments were not being
discarded when those segments were munmapped.  They are now.

Documentation updated.
