i386: Use int_nonimmediate_operand more

Pattern explosing and manual mode checks can be avoided by using
int_nonimmediate_operand special predicate.

While there, rewrite *x86_mov<SWI48:mode>cc_0_m1_neg_leu<SWI:mode>
to a combine pass splitter.

* config/i386/i386.md (*testqi_ext_3): Use
int_nonimmediate_operand instead of manual mode checks.
(*x86_mov<SWI48:mode>cc_0_m1_neg_leu<SWI:mode>):
Use int_nonimmediate_operand predicate.  Rewrite
define_insn_and_split pattern to a combine pass splitter.
