PR inline-asm/52813 revisited
The original patch for this PR made it an error to list the stack
pointer in the clobber list of an inline asm. However, the general
feeling seemed to be that going straight to a hard error was too harsh,
since there's quite a bit of existing code that has the clobber.
This patch implements the compromise discussed on IRC of making it
a -Wdeprecated warning instead.
