[libc][stdfix] Generate stdfix.h header with fixed point precision macros according to ISO/IEC TR 18037:2008 standard, and add fixed point type support detection. (#81255) Fixed point extension standard: https://standards.iso.org/ittf/PubliclyAvailableStandards/c051126_ISO_IEC_TR_18037_2008.zip

[libc] fix clang-tidy llvm-header-guard warnings (#82679) Towards the goal of getting `ninja libc-lint` back to green, fix the numerous instances of: warning: header guard does not follow preferred style [llvm-header-guard] This is because many of our header guards start with `__LLVM` rather than `LLVM`. To filter just these warnings: $ ninja -k2000 libc-lint 2>&1 | grep llvm-header-guard To automatically apply fixits: $ find libc/src libc/include libc/test -name \*.h | \ xargs -n1 -I {} clang-tidy {} -p build/compile_commands.json \ -checks='-*,llvm-header-guard' --fix --quiet Some manual cleanup is still necessary as headers that were missing header guards outright will have them inserted before the license block (we prefer them after).

[libc][stdfix] Use __FRACT_FBIT__ for fixed point support detection instead of compiler version. (#81820) Now that `__FRACT_FBIT__` and related macros are added in https://github.com/llvm/llvm-project/pull/81207, it is safer to use them for fixed point support detection, so that codes that do not use fixed point types will not fail to build when `-ffixed-point` is missing.
