AIX provides additional definitions in the system libc float.h that we
would like to be available to users, so we need to include_next through,
similar to what is done on some other platforms.
We also adjust the guards for some definitions which are restricted
based on language level to also be provide with the _ALL_SOURCE feature
test macro on AIX, similar to what is done by the platform float.h
header, so we don't run into cases where we don't provide the compiler
macro but still have a different definition from the system.

Summary:
These all had somewhat custom file headers with different text from the
ones I searched for previously, and so I missed them. Thanks to Hal and
Kristina and others who prompted me to fix this, and sorry it took so
long.

Summary:
In r353970, I enabled those features in C++11 and above. To be strictly
conforming, those features should only be enabled in C++17 and above.

Summary:
Previously, those #defines were only provided in C or when GNU extensions were
enabled. We need those #defines in C++11 and above, too.

Summary:
These macros are defined in the C11 standard and can be defined based on
the __*_HAS_DENORM__ default macros.

Summary:
The code defines __FLOAT_H and then includes the next <float.h>, which is
guarded on __FLOAT_H so it gets skipped entirely. This commit uses the header
guard __CLANG_FLOAT_H, like other headers (such as limits.h) do.

A test for this is checking if this compiles:
#include <float.h>
inline bool IsFinite(const double& number) {
return _finite(number) != 0;
}
That depends however on either mingw or msvc being installed, and
chapuni tells me there might be issues with float.h on mingw, so
no automated test is added.
