* posix/src/mqueuetimedreceive.c, posix/src/mqueuetimedsend.c,
posix/src/mutextimedlock.c, posix/src/prwlocktimedrdlock.c,
posix/src/prwlocktimedwrlock.c, posix/src/semtimedwait.c: Switch from
switch to if's because only one value needed to be tested. This
shrinks the code and makes it easier to do coverage analysis on.
