[mips][msa] Remove range checks for non-immediate sld.[bhwd] instructions

[smaksimovic]

Summary

Removes immediate range checks for these instructions, since they have GPR rt as their input operand.

LGTM. Minor nit: there's some spurious whitespace that can be removed, see my inlined comment.

I'm seeing some whitespace here in the patch, remove it before committing please.

Removed whitespace.
