Increment/decrement vector by multiple of predicate constraint
element count.
The variants added by this patch are:
- INCH, INCW, INC
and (saturating):
- SQINCH, SQINCW, SQINCD
- UQINCH, UQINCW, UQINCW
- SQDECH, SQINCW, SQINCD
- UQDECH, UQINCW, UQINCW
For example:
incw z0.s, all, mul #4

These patches were previously reverted as they led to
buildbot time-outs caused by large switch statement in
printAliasInstr when using UBSan and O3. The issue has
been addressed with a workaround (r335525).

This patch uses the DiagnosticPredicate for SVE predicate patterns
to improve their diagnostics, now giving a 'invalid operand' diagnostic
if the type is not an immediate or one of the expected pattern
labels.

The variants added by this patch are:
- SQINC signed increment, e.g. sqinc x0, w0, all, mul #4
- SQDEC signed decrement, e.g. sqdec x0, w0, all, mul #4
- UQINC unsigned increment, e.g. uqinc w0, all, mul #4
- UQDEC unsigned decrement, e.g. uqdec w0, all, mul #4
This patch includes asmparser changes to parse a GPR64 as a GPR32 in
order to satisfy the constraint check:
x0 == GPR64(w0)
in:
sqinc x0, w0, all, mul #4
^___^ (must match)
