[Bug inline-asm/38925] gcc ignores use of %rbp via assembly, generates bad code

[hpreg at vmware dot com]

Andrew,

With respect to your comment #2: initializing all the variables to 0 does not
solve the problem, which is that gcc does not understand that %rbp is
clobbered.

With respect to your comment #3: as explained in the bug description, it is
_not_ possible to mark r8 through r15 as clobbered in an inline-asm statement.
Hence the "mess".
