x86-64: Use fxsave/xsave/xsavec in _dl_runtime_resolve -
In _dl_runtime_resolve, use fxsave/xsave/xsavec to preserve all
vector, mask and bound registers. It simplifies _dl_runtime_resolve
and supports different calling conventions. ld.so code size is reduced
by more than 1 KB. However, use fxsave/xsave/xsavec takes a little bit
more cycles than saving and restoring vector and bound registers
individually.
Target Release: 16.04.4
