After a prefix match, the old code advanced the length of the
prefix.  This is incorrect since the full match might begin
in the middle of the prefix. (Consider "aaaab+" matching
"aaaaaab").

The bug was that for an anchored pattern such as ^x, the prefix
scan ignored the anchor, and could scan the whole file if there was
no x present.  The fix is to do prefix matching after the anchor;
the cost miniscule; the speedups huge.

	This is really insignificant, but it might as well be fixed.

Implementation uses fast suffixarray lookup to find
initial matches if the regular expression starts with
a suitable prefix without meta characters.

#pragma dynexport is no longer needed for
this use of cgo, since the gcc and gc code are
now linked together into the same binary.
It may still be necessary later.

On the Mac, you cannot use the GOT to resolve
symbols that exist in the current binary, so 6l and 8l
translate the GOT-loading mov instructions into lea
instructions.

On ELF systems, we could use the GOT for those
symbols, but for consistency 6l and 8l apply the
same translation.

The translation is sketchy in the extreme
(depending on the relocation being in a mov
instruction) but it verifies that the instruction
is a mov before rewriting it to lea.

Also makes typedefs global across files.

The former is a boolean function to test whether a string
contains a regular expression metacharacter; the second
returns the string used to compile the regexp.
