A32: Implement ARM-mode CRC32 instructions
...
Implements the ARM-mode variants of the CRC32 instructions introduced
within ARMv8. This is also one of the instruction cases where there is
UNPREDICTABLE behavior that is constrained (we must do one of the
options indicated by the reference manual).
In both documented cases of constrained unpredictable behavior, we treat
the instructions as unpredictable in order to allow library users to
hook the unpredictable exception to provide the intended behavior they
desire.

Generally hash functions shouldn't throw exceptions. It's also a

allow it to play nicer with it.
While we're at it, we can also make the std::less specializations

A64: Handle reserved instruction cases more specifically where applicable
...
These are cases that are defined as reserved within the ARMv8 reference
manual, so we can handle them as such instead of as unallocated
encodings.
While this doesn't actually change emulated behavior, it does at least
allow the JIT to generate the more appropriate exception.

simd_scalar_shift_by_immediate: Change UnallocatedEncoding() path in SaturatingShiftLeft to ReservedValue()

Strictly speaking, immh being zero is defined as reserved in the ARMv8
reference manual. This was just an error on my part when introducing the
SQSHL immediate scalar variant.

Due to promotion rules (types < int, even if unsigned, get promoted to
int when arithmetic is performed on them), this is a potential spot for
undefined behavior.
