  [lldb] [Process/Linux] Support arbitrarily-sized FPR writes on ARM

Support arbitrarily-sized FPR writes on ARM in order to fix writing qN
registers directly.  Currently, writing them works only by accident
due to value_regs splitting them into smaller writes via dN and sN
registers.

  Log Message:
  -----------
  [lldb] [Process/Utility] Fix value_regs/invalidate_regs for ARM

Fix incorrect values for value_regs, and incomplete values for
invalidate_regs in RegisterInfos_arm.  The value_regs entry needs
to list only one base (i.e. larger) register that needs to be read
to get the value for this register, while invalidate_regs needs to list
all other registers (including pseudo-register) whose values would
change when this register is written to.

7a8ba4ffbeecb5070926b80bb839a4d80539f1ac fixed a similar problem
for ARM64.

  -----------
  [lldb] [ABI/X86] Support combining xmm* and ymm*h regs into ymm*

gdbserver does not expose combined ymm* registers but rather XSAVE-style
split xmm* and ymm*h portions.  Extend value_regs to support combining
multiple registers and use it to create user-friendly ymm* registers
that are combined from split xmm* and ymm*h portions.
