See #18351 for details on the specifications.
This is the same thing NetBSD does. BeOS R5 defined these values
differently than we did even before this commit, and it does not
seem to have caused problems then, so this should be fine.
While technically an ABI break, in practice these values are not
always differentiated on other platforms, and it appears musl's
code triggers divide-by-zero exceptions on purpose before it
returns this value, anyway.
Fixes#18351.
glibc does the same. Technically, some of these builtins did
not exist / did not work before GCC 4.4, but the source tree
cannot be compiled with a version that old anyway.
x86_64 and _x86 need to keep the old functions for now, of
course; but all other architectures can probably feel free
to drop the s_isnan, etc. functions from their glibc.
This will make upcoming patches easier...

* whitespace cleanup and renamed log2() to radeon_log2 (conflicts with log2 in math.h)

define the HUGE_VAL and friends macros to the respective __builtin_*()
functions.

Cleaned up some header style violations, making sure there are two blank lines after the header guards.
This fixes the posix header part of #2191.

* copied implementations for llround(), llroundf() and llroundl() from
glibc-2.3.2
* added corresponding declarations to math.h

* Replaced all occurences with the standard macros M_PI, and M_PI_2.
* Some coding style cleanup on the touched files, no other changes besides
adding a missing check for a failed memory allocation.

Replaced single-line comments by multi-line comments for ANSI C
compliance.

hack math_huge_val_ifndef does, anyway. We do it ourselves and remove
the therefore superfluous gcc math.h header.
