[clang] Search for @_thisIsNotAPipe vs _thisIsNotAPipe (PR #192132)

[Sean Perry via cfe-commits]

https://github.com/perry-ca created https://github.com/llvm/llvm-project/pull/192132

z/OS has a table of mapped names in the IR.  Counting the hits for just the name leads to one more hit than expected.  Search for the name with the @ char to make sure the right occurrences are being counted.
