middle-end/32667 - document cpymem and memcpy exact overlap requirement
The following amends the cpymem documentation to mention that exact
overlap needs to be handled gracefully, also noting that the target
runtime is expected to behave the same way where -ffreestanding
docs mention the set of routines required.
PR middle-end/32667
* doc/md.texi (cpymem): Document that exact overlap of source
and destination needs to work.
* doc/standards.texi (ffreestanding): Mention memcpy is required
to handle the exact overlap case.
