My bad, this should be "!=" NULL. I will send a v2 when I get more
feedback.

This removes the hotspot in parse_file_seq's call to strpbrk, by using
SSE2 vector instructions. The resulting speedup on QEMU's noop build
is around 6% (15.4 seconds to 14.5).
The code is roughly based on GCC's similar optimizations in the lexer.

* read.c (parse_file_seq): Us
