This patch extends the PredicateMethod of AsmOperands used in SVE's 
LD1 instructions with a DiagnosticPredicate. This makes them 'context
sensitive' to the operand that has been parsed and tells the user to
use the right register (with expected shift/extend), rather than telling 
the immediate is out of range when it actually parsed a register.

Patch [2/2] in a series to improve assembler diagnostics for SVE.
