7f920e2e - [NFC][clang] Split clang/lib/CodeGen/CGBuiltin.cpp into target-specific files (#132252)

[NFC][clang] Split clang/lib/CodeGen/CGBuiltin.cpp into target-specific files (#132252) clang/lib/CodeGen/CGBuiltin.cpp is over 1MB long (>23k LoC), and can take minutes to recompile (depending on compiler and host system) when modified, and 5 seconds for clangd to update for every edit. Splitting this file was discussed in this thread: https://discourse.llvm.org/t/splitting-clang-s-cgbuiltin-cpp-over-23k-lines-long-takes-1min-to-compile/ and the idea has received a number of +1 votes, hence this change.
