  Handle leading underscores in update_cc_test_checks.py (#121800)

For some ABIs `update_cc_test_checks.py` is unable to generate tests
because of the mismatch between the mangled function names reported by
clang's `-asd-dump` and the function names in LLVM IR.

This patch fixes it by striping the leading underscore from the mangled
name for global functions if the data layout string says they have one.
