[clang] [CodeGen][NFC] Move test builtin_signbit.cpp to CodeGen (PR #127814)

[Donát Nagy via cfe-commits]

https://github.com/NagyDonat created https://github.com/llvm/llvm-project/pull/127814

Because it is one of the three "misplaced" test files that appeared under `/clang/test/Analysis` but were unrelated to the clang static analyzer. For background see the following discourse thread: https://discourse.llvm.org/t/taking-ownership-of-clang-test-analysis/84689/2

I placed this file in `clang/test/CodeGen` because as far as I see it tests the code generated from `__builtin_signbit` (and there are many other `builtin_*` test files in that directory); but I'm not familiar with that area, so I'm not certain that it's the best place.
