[compiler-rt] [compiler-rt] fix gcc <13 support by removing enum-type-specifier (PR #165034)

[Yuxuan Chen via llvm-commits]

https://github.com/yuxuanchen1997 created https://github.com/llvm/llvm-project/pull/165034

This `unsigned int` here is a new addition introduced in https://github.com/llvm/llvm-project/pull/164713 and doesn't compile under older (<13) gcc, which LLVM officially supports from 7.4+.
