Milad Fa 896f9c23da cppgc: fix sourceLocation test on gcc
This test produces different outputs when compiled with
gcc. It is currently failing on PPC using gcc-8, it also has
failed on riscv: https://github.com/riscv/v8/issues/174

I have also tested it with gcc-10 on x64 and it still fails.
The line numbers seem to be different when compiled with gcc
instead of clang.

As a workaround we can force the usage of macros in one line
to assure outputs are the same on either compiler.
