4b555934 - [compiler-rt] Fix a bug introduced into DEFINE_COMPILERRT_FUNCTION_ALIAS (#156979)

[compiler-rt] Fix a bug introduced into DEFINE_COMPILERRT_FUNCTION_ALIAS (#156979) ... during a refactoring for arm64ec in #137960 6ade80ce18087b1e27505985a254c487679e16b8. The subtle change here results in a change in symbols in the library from: ``` 00000038 T ___gesf2 00000038 T ___gtsf2 ``` to: ``` I ___gesf2 (indirect for __gtsf2) 00000038 T ___gtsf2 ``` ... which is a breaking change on Mach-O platforms. rdar://157846316
