ir/value: Add member function to check whether or not all bits of a contained value are set
...
This is useful when we wish to know if a contained value is something
like 0xFFFFFFFF, as this helps perform constant folding. For example the
operation: x & 0xFFFFFFFF can be folded to just x in the 32-bit case.

constant_propagation_pass: Fold EOR operations
...
It's possible to fold cases of exclusive OR operations if they can be
known to be an identity operation, or if both operands happen to be known
immediates, in which case we can just store the result of the
exclusive-OR directly.

Fix VShift terminology
...
An arithmetic shift is by definition a signed shift, and a logical shift is by definition an unsigned shift.
- Rename VectorLogicalVShiftS* -> VectorArithmeticVShift*

Fixes decoding for 64-bit instructions
Does not help/apply to any currently supported ARM versions (since
all are 32-bit length or below), it's for future-proofing should
such an arch be supported.

A64/imm: Add full range of comparison operators to Imm template

Makes the comparison interface consistent by providing all of the

the Imm instance by value, as it's really only a u32 under the covers,
and it's cheaper to shuffle around a u32 than a 64-bit pointer address.
