Fix the Rn register encoding for both SSAT and USAT. Update the parsing of the
shift operand to correctly handle the allowed shift types and immediate ranges
and issue meaningful diagnostics when an illegal value or shift type is
specified. Add aliases to parse an ommitted shift operand (default value of
'lsl #0').

Add tests for diagnostics and proper encoding.

Addresses PR10466, although the crash from that PR only triggers in cases where DAGCombine misses optimizing a shuffle.

The shift immediate encoding, printing, etc. is handled directly by the
enclosing operand definition, so it should be a vanilla immediate, not a
nested complex operand (shift_imm).

Update the comment. This feature is available only on Darwin at the moment. Though it's not Darwin-specific.

Remove some inititalizers that are the same as the default, move defs next to
their (singular) uses and generally simplify some formatting of asm operand
definitions.

unwind encoding for that function. This simply crawls through the prolog looking
for machine instrs marked as "frame setup". It can calculate from these what the
compact unwind should look like.

This is currently disabled because of needed linker support. But initial tests
look good.

The immediate is in the range 1-32, but is encoded as 0-31 in a 5-bit bitfield.
Update the representation such that we store the operand as 0-31, allowing us
to remove the encoder method and the special case handling in the disassembler.
Update the assembly parser and the instruction printer accordingly.
