[ELF] Support . and $ in symbol names in expressions GNU ld supports `.` and `$` in symbol names while LLD doesn't support them in `readPrimary` expressions. Using `.` can result in such an error: ``` https://github.com/ClangBuiltLinux/linux/issues/1318 ld.lld: error: ./arch/powerpc/kernel/vmlinux.lds:255: malformed number: .TOC. >>> __toc_ptr = (DEFINED (.TOC.) ? .TOC. : ADDR (.got)) + 0x8000; ``` Allow `.` (ppc64 special symbol `.TOC.`) and `$` (RISC-V special symbol `__global_pointer$`). Change `diag[3-5].test` to use an invalid character `^`. Note: GNU ld allows `~` in non-leading positions of a symbol name. `~` is not used in practice, conflicts with the unary operator, and can cause some parsing difficulty, so this patch does not add it.
