[ARM] Delay creation of MVE Imm shifts to legalization
The reasoning for creating VSHLIMM/VSHRsIMM/VSHRuIMM nodes in a combine
- because matching i64 constants is difficult - does not apply for MVE,
as there are not v2i64 shifts. Delaying the creation of the nodes can
allow extra transforms on target independant shl/shr.
