string-util: rework memory_erase() to not use GCC optimize attribute (#3812)
"#pragma GCC optimize" is merely a convenience to decorate multiple
functions with attribute optimize. And the manual has this to say about
this attribute:
This attribute should be used for debugging purposes only. It
is not suitable in production code.
Some versions of GCC also seem to have a problem with this pragma in
combination with LTO, resulting in ICEs.
So use a different approach (indirect the memset call via a volatile
function pointer) as implemented in openssl's crypto/mem_clr.c.
Closes: #3811
