13f7786f72 [libc] Remove trivial .h.def files (#149466) 
Remove all the .h.def files that already express nothing
whatsoever not already expressed in YAML.  Clean up a few YAML
files without materially changing any generated header output.

Many more .h.def files remain that need a bit of conversion in
YAML to express macro requirements and such.

e908f6131e [libc] Fix WEOF and fix 1'000'000 error messages on test failure (#147928) 
1. WEOF is defined as a `wint_t` by the C standard. On certain
architectures, the test won't compile on `-Wall`. This fixes it.
2. If `testSubnormalRange` fails, it will spit out way too many error
messages, which overwhelms my test environment. I reduce this to 1k for
now.

This is required for #145349
