another testcase

Here's another testcase that I just simplified from my attempts to use, in
Mozilla, some SSE2 code with runtime detection using CPUID.  (See
https://bugzilla.mozilla.org/show_bug.cgi?id=506430 and
https://bugzilla.mozilla.org/show_bug.cgi?id=513422 .)

I'd simplified this testcase before discovering the existing bug report.

When I compile this testcase with:
/usr/local/gcc-4.4.1/bin/gcc -mno-sse2 ice.c
I get:
ice.c: In function ‘Convert_ascii_run’:
ice.c:11: internal compiler error: in emit_move_insn, at expr.c:3405
