[PATCH] D10476: Additional fix for PR14269: Clang crashes when a bit field is used as inline assembler input / output with memory constraint

[Eric Christopher]

This seems to be a bit overconstrained versus what gcc accepts on the testcase:

dzur:~/tmp> gcc -S baz.c                                                                               |

also, the precision in error messages is nice. :)
