Add a proper support for several MIPS instructions that generate SigFPE.

Add support to properly handle TEQ, ADD and SUB instructions that generate
exceptions on MIPS platforms. A SignalException test for MIPS32 has also been
added, so we can cover more cases.

This resolves:

none/tests/faultstatus
gdbserver_tests/mcsignopass
gdbserver_tests/mcsigpass
