The new ia64 assembler is incompatible with glibc

[H. J. Lu]

After applied 2 patches enclosed here, I can compile glibc in CVS. But
I got so many failures in "make check":

make[4]: ***
[/export/build/gnu/glibc-nptl/build-ia64-linux/math/basic-test.out]

Error 1

It looks like the math functions are wrong. Replacing the new assembler
with the old one fixes the problem.
