Gdbserver: Implement enough to reach gdb prompt
...
Memory is implemented, but without any checking or
invalidation.
Registers just hardcode a RIP for my test elf.
But GDB can read the elf over tcp, initilize and allow you to create breakpoints, which get
writen back before continue (which is not hooked up)

Fixes bug in PUSH op with RSP source.

We were modifying RSP to adjust the stack first.

`push [rsp]` was broken before this

Fixes issues with PSLLDQ and PSRLDQ
...
These are whole vector shift instructions and they shift by bytes rather
than bits.
You only get an immediate offset for the instruction.
Implements two new IR ops to account for these instructions
This also doesn't match AArch64 behaviour 100%, requires two
instructions to emulate rather than the single one on the x86-side
