e05858a0f8 Work around clang bug.
https://godbolt.org/z/zedh7rrhc

This is similar to https://github.com/llvm/llvm-project/issues/47746,
except I needed to use a different workaround.

6d2fb68f5c Simplify to_float
* Use right-sized uint type for bit fiddling
** This removes the need to special casing on endianness
* Replace ternary with just shifting the sign at the right place
** This seems to improve codegen (less instructions, no cmov)

61f4840188 Make endianness detection more portable
The current check for endianness fails on platforms using newlib as the
C library, because it provides <machine/endian.h> not <endian.h>. This
could be fixed by adding `|| defined(__NEWLIB__)` to the check for
targets that provide <machine/endian.h> (i.e. BSD-like targets).

A more portable solution is to just check if the compiler has already
defined the necessary macros (which is true for GCC and Clang and Intel,
at least). Then no header is needed, and it works for platforms that
aren't explicitly listed in the conditionals.
