Sander de Smalen c504101781 [AArch64][SVE] Asm: Support for (saturating) vector INC/DEC instructions.
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

Sander de Smalen 0325e304b9 Reapply r334980 and r334983.
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).

Vlad Tsyrklevich 98724e582e Revert r334980 and 334983
This reverts commits r334980 and r334983 because they were causing build
timeouts on the x86_64-linux-ubsan bot.

Sander de Smalen 067eee1c13 [AArch64][SVE] Asm: Fix predicate pattern diagnostics.
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.

Sander de Smalen 7ac9e193ec [AArch64][SVE] Asm: Support for saturating INC/DEC (32bit scalar) instructions.
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)
