While it does feel familiar, it is slightly different.

That case was both compilers validating the inline asm, yet generating
assembly that the assembler would choke on.  This case is validation
in the front end failing.

Side note: would you mind sending a review by tag for v5 of that patch
if you think it's good to go?  It does fix a regression I'd prefer
didn't ship in 5.7.
