The emitted assembly exhibiting the ordering problem
This is on x86_64, compiled with -Os. In the attached assembly, line 89, .L55,
.cfi_restore is emitted for ebx and ebp after .cfi_def_cfa_offset 8 already
invalidated the location where they were stored. cfa_offset should be emitted
after cfi_restores, as it was in the other codepaths like .LEHE0-.L51
