[PATCH] [ARM64] Improve diagnostics for Cn operands in SYS instructions

[Bradley Smith]

Hi t.p.northover,

This patch slightly tidies up the Cn operand parsing and emits better diagnostics if parsing fails.

As with my previous patches, there is no testcase for this as it is part of the merge of MC/AArch64/basic-a64-diagnostics.s.
