Print the first indexed element as a FP register, for example:
mov z0.d, z1.d[0]
Is now printed as:
mov z0.d, d1
Next to printing, this patch also adds aliases to parse 'mov z0.d, d1'.

Unpredicated copy of indexed SVE element to SVE vector,
along with MOV-aliases.
For example:
dup z0.h, z1.h[0]
duplicates the first 16-bit element from z1 to all elements in
the result vector z0.

Unpredicated copy of optionally-shifted immediate to SVE vector,
along with MOV-aliases.
This patch contains parsing and printing support for
cpy_imm8_opt_lsl_(i8|i16|i32|i64). This operand allows a signed value in
the range -128 to +127. For element widths of 16 bits or higher it may
also be a signed multiple of 256 in the range -32768 to +32512.
For element-width of 8 bits a range of -128 to 255 is accepted, since a copy
of a byte can be considered either signed/unsigned.
Note: This patch renames tryParseAddSubImm() -> tryParseImmWithOptionalShift()
and moves the behaviour of trying to shift a plain immediate by an allowed
shift-value to its addImmWithOptionalShiftOperands() method, so that the
parsing itself is generic and allows immediates from multiple shifted operands.
This is done because an immediate can be divisible by both shifted operands.
