No need to discard translation in gdbserver when --vgdb=full
is given, as all instructions are in any case instrumented when
full is given.

This is (slightly) more efficient for full, and allows
to bypass the arm64 discard_translation problem caused by unchain
missing

Mention that --vgdb=full bypasses the discard_translation gdbsrv problem

arm64: implement the apply on all GP register.
This is needed for leak search to work properly/not crash.
