minimized repro case

When compiling the attached min.E file, clang emits alignment (I think) syntax
(":128") that is unrecognized by the system assembler:

~/src/wr/trunk/third_party/llvm-build/Release+Asserts/bin/clang  -Os -arch
armv7 -no-integrated-as -x c -c /tmp/min.E -o /dev/null
var/folders/00/0871r000h01000cxqpysvccm0010w7/T/min-c96ef1.s:19:']' expected --
`vst1.64 {d8,d9},[r4:128]'
/var/folders/00/0871r000h01000cxqpysvccm0010w7/T/min-c96ef1.s:46:']' expected
-- `vld1.64 {d8,d9},[r4:128]'
clang: error: assembler command failed with exit code 1 (use -v to see
invocation)


This is on OSX 10.8.4, xcode 4.6.3 is installed (which is where I'm guessing
the /usr/bin/as binary comes from).
