Joseph Myers b08d204a37 softfloat: merge floatx80_mod and floatx80_rem ... The m68k-specific softfloat code includes a function floatx80_mod that is extremely similar to floatx80_rem, but computing the remainder based on truncating the quotient toward zero rather than rounding it to nearest integer. This is also useful for emulating the x87 fprem and fprem1 instructions. Change the floatx80_rem implementation into floatx80_modrem that can perform either operation, with both floatx80_rem and floatx80_mod as thin wrappers available for all targets. There does not appear to be any use for the _mod operation for other floating-point formats in QEMU (the only other architectures using _rem at all are linux-user/arm/nwfpe, for FPA emulation, and openrisc, for instructions that have been removed in the latest version of the architecture), so no change is made to the code for other formats.
