c: add more exceptions to -Wno-*
Commit eca1ac18dc1978b15b500c9f1710c05cb1ccc0ec (#14252) added support
for properly detecting the -Wno-vla-larger-than flag: a value must be
specified for its positive form (-Wvla-larger-than=N), or GCC will exit
with the error "missing argument to ‘-Walloc-size-larger-than=’".
There is a handful of other -Wno-* flags whose positive form act in the
same manner, but are not covered here:
* -Wno-alloc-size-larger-than (GCC >=7.1.0)
* -Wno-alloca-larger-than (GCC >=7.1.0)
* -Wno-frame-larger-than (GCC >=4.4.0)
* -Wno-stack-usage (GCC >=4.7.0)
Add logic to treat these in the same way.
