Joseph Myers 26e4810210 Rename fromfp files in preparation for changing types for C23 
As discussed in bug 28327, the fromfp functions changed type in C23
(compared to the version in TS 18661-1); they now return the same type
as the floating-point argument, instead of intmax_t / uintmax_t.

As with other such incompatible changes compared to the initial TS
18661 versions of interfaces (the types of totalorder functions, in
particular), it seems appropriate to support only the new version as
an API, not the old one (although many programs written for the old
API might in fact work wtih the new one as well).  Thus, the existing
implementations should become compat symbols.  They are sufficiently
different from how I'd expect to implement the new version that using
separate implementations in separate files is more convenient than
trying to share code, and directly sharing testcases would be
problematic as well.

Rename the existing fromfp implementation and test files to names
reflecting how they're intended to become compat symbols, so freeing
up the existing filenames for a subsequent implementation of the C23
versions of these functions (which is the point at which the existing
implementations would actually become compat symbols).

gen-fromfp-tests.py and gen-fromfp-tests-inputs are not renamed; I
think it will make sense to adapt the test generator to be able to
generate most tests for both versions of the functions (with extra
test inputs added that are only of interest with the C23 version).
The ldbl-opt/nldbl-* files are also not renamed; since those are for a
static only library, no compat versions are needed, and they'll just
have their contents changed when the C23 version is implemented.

Tested for x86_64, and with build-many-glibcs.py.
