LoongArch: Add flogb.{s,d} instructions and expand logb{sf,df}2
On LoongArch, flogb instructions extract the exponent of a non-negative
floating point value, but produces NaN for negative values. So we need
to add a fabs instruction when we expand logb.
gcc/ChangeLog:
* config/loongarch/loongarch.md (UNSPEC_FLOGB): New unspec.
(type): Add flogb.
(logb_non_negative<mode>2): New instruction template.
(logb<mode>2): New define_expand.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/flogb.c: New test.
