This series contains mostly cosmetic FPU cleanups aimed to make
source code recognition easier for tools like gdb, gcov, calgrind,
and others.
There is also a patch that refactors conversion from ieee to mips
fp exception flags. This refactoring will improve the performance
of almost all fp-related mips instructions, albait very modestly
(less that one percent).
There is a patch that introduces some logging in mips_malta.c.
There is a patch on change of Aleksandar Rikalo's email.
Finally, there is a patch on renaming some files in hw/mips folder.
v3->v4:
- corrected some spelling and style mistakes in commit messages
- added a patch on renaming some files in hw/mips
v2->v3:
- changed Malta patch to perform logging
- added change of Aleksandar Rikalo's email
v1->v2:
- added more demacroing

This is just a cosmetic change to enable tools like gcov, gdb,
callgrind, etc. to better display involved source code.

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.
