Subjectfyi: gcc33-hammer crashes when compiling kvm emulate.c

While doing a test run with the minimum supported compiler
I found:

An old gcc 3.3-hammer segfaults when compiling the current KVM
emulate.c (or rather in x86_emulate_insns) on x86-64.

The compiler goes into an endless recursion in validate_rtx and then
eventually overflows the stack and dies.

I minimized a test case, but didn't find a workaround
(minimized test case

My guess it's related to some of the inline assembler uses.

This might be an excuse to bump the minimum compiler version again.
