gccrs: Fix infinite loop with missing comma
A missing comma between inline assembly templates did not throw an error
and looped indefinitely.
gcc/rust/ChangeLog:
* expand/rust-macro-builtins-asm.cc (parse_format_strings): Emit an
error when expecting a comma.
gcc/testsuite/ChangeLog:
* rust/compile/issue-4006.rs: New test.
