* i386: For integer comparisons with zero, emit "test $-1,%reg" instead of "test %reg,%reg". It is more spilling-friendly, because it transforms into "test $-1,spilltemp" and does not require a register.

* tx86addnode.second_cmpfloatsse and tx86addnode.second_cmpfloatavx are identical except instruction opcodes -> merged into second_cmpfloatvector, cleaned up, and allowed constant operands at both sides.

* Let tx86addnode.check_left_and_right_fpureg() act as when its argument was=true (removed argument and renamed to force_left_and_right_fpureg). Its action when force_fpureg=false is now coded separately.
