* fix handling of invalid arguments (was jumping to wrong label!)
...
(found by... running the regress test!)
* clean up punctuation.
* create a proper frame for the child fn that follows the o32 calling
conventions. In particular, leave 4 stack slots that the child
fn can write on, put the GP above them, and invoke .cprestore
properly in light of the child fn arg area. (realized it was a
problem upon inspection, verified using the regress test compiled
-O0.)

looks like nobody ever seriously tried the _REENTRANT version of this
...
code (which, uh, seems the default for a fresh build)... it wasn't
setting up v1 properly (the instruction to set up v1 was after the
return jump, in "reorder" code... i.e. after the end of the function).
That would break error returns from 64-bit syscalls (e.g. checks
in dd and who knows what else) to see if input or output are pipes.
It looks like the non-_REENTRANT version was broken (on the nathanw-sa
branch) in rev 1.9.2.1 and fixed in 1.9.2.2, but the _REENTRANT version
was never fixed, and the broken bits were merged back on to the trunk.

Enable the libc-provided signal trampoline. The old __sigaction14
...
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).
No shared library version change is necessary; no new symbols

Clean up some rampant code duplication wrt ieee number handling:
...
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
