Fixes Issue #27983: Cause lack of llvm-profdata tool when using clang as
required for PGO linking to be a configure time error rather than make time when --with-optimizations is enabled. Also improve our ability to find the llvm-profdata tool on MacOS and some Linuxes.

-----------------
|

|

- Issue #27983: Cause lack of llvm-profdata tool when using clang as
|
||||
required for PGO linking to be a configure time error rather than
|
||||
make time when --with-optimizations is enabled. Also improve our
|
||||
ability to find the llvm-profdata tool on MacOS and some Linuxes.
|
||||
|
||||
- Issue #26307: The profile-opt build now applys PGO to the built-in modules.
|
||||
|
||||
- Issue #27078: Added BUILD_STRING opcode. Optimized f-strings evaluation.
