Unify signbitl implementations. (Unclear why they were different, it was only the comments that differed)
Add a comment describing why the generic version works for both 80-bit and 128-bit double.

Don't include sigtramp or foocontext routines in rumprun mode. They won't work (since a rump kernel does not provide NetBSD _lwp syscalls nor signals), but they cause unwanted symbols to be pulled in when the resulting libc is linked.

Remove "objects built from C sources" comments. Everyone can see they're built from C sources because the source files end in .c (???)

Push back the descriptions of NaN formats, and descriptions of the distinction between signalling NaNs and quiet NaNs back into the machine-dependent headers; treat the implementation of __nanf in the same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs to the implementation, and unlike our headers used to suggest they're not identical in the interpretation of the fraction's MSb; in due course, make those of hppa, mips, sh3, and sh5 reflect reality.

Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES. This is a change of behaviour. If a Makefile wants the clean semantics it must specifically append to CLEANFILES. Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".

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).
