soft-fp: Use parentheses around macro arguments.

This patch cleans up the soft-fp code to use parentheses around macro
arguments (where possible; many macro arguments are identifiers used
with ## rather than arbitrary expressions, so cannot be put in
parentheses).  (I'm not aware of any bugs caused by the lack of
parentheses, but this is generally good practice.  The patch is not
exhaustive regarding internal macros where the arguments always come
directly from the mantissa of a floating-point number, although
probably those should be cleaned up in this regard as well.)

Tested for powerpc-nofpu that the installed shared libraries are
unchanged by this patch.
