Eliminate the remaining swith-case code for register getters,
and migrate YMM registers to regset-oriented model. Since these
registers are recombined from XMM and YMM_Hi128 XSAVE blocks, while LLDB
gdb-server protocol transmits YMM registers whole, the offset-based
model will not work here. Nevertheless, some improvement was possible.
Replace generic 'XSaveRegSet' along with sub-sets for XSAVE components
with 'YMMRegSet' (and more regsets in the future as further components
are implemented). Create a helper GetYMMSplitReg() method that obtains
pointers to the appropriate XMM and YMM_Hi128 blocks to reduce code
