Currently the emulation of VSTRS recognizes partial matches in presence
of \0 in the haystack, which, according to PoP, is not correct:
If the ZS flag is one and a zero byte was detected
in the second operand, then there can not be a
partial match ...
Add a check for this. While at it, fold a number of explicitly handled
special cases into the generic logic.

move everything related to translate, as well as HELPER code in tcg/
mmu_helper.c stays put for now, as it contains both TCG and KVM code.
After the reshuffling, update MAINTAINERS accordingly.
Make use of the new directory:
