-mno-gen-cell-microcode is a pain to handle correctly: it causes
different code generation for some very basic patterns, even patterns
specific to that option.  It also requires marking up many patterns,
which is a pain when adding new patterns or modifying existing ones
(first non-trivial step is finding the Cell BE manual!)

-mwarn-cell-microcode is very expensive, even more so after my recent
fix for PR43763; and it used to ICE for seven years before that fix.

This patch removes both these command line options (it leaves the
positive form of -mgen-cell-microcode, doing nothing, for
compatibility).

Where cc_reg_not_micro_cr0_operand was used, we now get the regular
cc_reg_not_cr0_operand.

One testcase used -mgen-cell-microcode and one its negation; both
are adjusted.
