It seems to compile properly. I didn't test the resulting code though. 
The svn version of clang I used (trunk 103935) didn't mind these 
extensions and worked with your vanilla code.

The ubuntu version here didn't work:
clang version 1.1 (branches/release_27)

As for the ICC compiled code, it seems that for index 0-15 everything is 
computed right, and it fails between 16 and 127.

A working fix is to replace the line :

typedef __m128i vtype;

by

typedef unsigned long long vtype __attribute__ ((vector_size (16)));

(int doesn't work for some reason)

Pukes a ton of warnings, but -test seems to work fine.
