uml: improve detection of host cmov
This patch introduces a new way of checking for the cmov instruction. I use
signal handling instead of reading /proc/cpuinfo.
[ jdike - Fiddled the asm to make it obvious that it didn't mess with
any in-use registers and made test_for_host_cmov void ]
[akpm@linux-foundation.org: coding-style fixes]
