Additional fixes for llvm-as
Unlike GCC, llvm always uses an integrated assembler, which attempts to
recognized all `asm` statements written in the C code. glibc uses some
syntactically invalid asm statements to emit constants into assembly that
are later extracted with a sed or AWK script.
This change fixes two such invalid `asm` statements by wrapping the
output in a `.ascii` directive.. This does not break the sed/AWK (the same
special sequence is output) but it makes the statement syntactically valid.
See cf8e3f8757 for a previous fix for the same issue.
