2020-07-14target/mips: Fix ADD.S FPU instructionAlex Richardson
After merging latest QEMU upstream into our CHERI fork, I noticed that some of the FPU tests in our MIPS baremetal testsuite [*] started failing. It turns out commit 1ace099f2a accidentally changed add.s into a subtract.

2020-06-09target/mips: fpu: Refactor conversion from ieee to mips exception flagsAleksandar Markovic
The original coversion function is used for regular and MSA floating point instructions handling. Since there are some nuanced differences between regular and MSA floating point exception handling, provide two instances of the conversion function, rather than just a single common one. Inline both instances of this function instances for the sake of performance. Improve variable naming in surrounding code for clarity.
