[Patch][AArch64] Shift right pattern fix

[Alex Velenko]

Hi,
This patch fixes shift right pattern, as it failed on -O0 after shift
right patch. The reason was unnecessary movement of immediate value to
a register due to type mismatch.
Patch is tested not to cause any additional regressions.
Could someone, please, approve and commit this patch, as I do not have
the rights to do so?

Kind regards,
Alex
