Sean Callanan 677f2a263a Fixed a problem where the HasAVX() code in 
debugserver did not back up %ebx/%rbx, even
though it was being clobbered by the CPUID
instruction.

Sean Callanan c4ffe37cf1 Added support for dynamic detection of AVX, and 
fixed a few bugs that revealed.  Now the "register
read" command should show AVX registers
(ymm0-ymm15) on Mac OS X platforms that support
them.

When testing this on Mac OS X, run debugserver
manually, like this:

debugserver --native-regs localhost:1111 /path/to/executable

Then

lldb /path/to/executable
...
(lldb) process connect connect://localhost:1111
