eric fang 8d77e45064 cmd/compile: fix bug of conditional instructions on arm64 
CL 302231 added some optimization rules with instructions CSETM, CSINC,
CSINV, and CSNEG, but did not deal with the situation where flag is
constant, resulting in some cases that could be more optimized cannot
be optimized, and the FlagConstant value is passed to codegen pass. This
CL adds these missing rules.

Fixes #45359
