Please make sure to have in a separate patch or multiple patches the correctness fixes and maybe anything unrelated to instantiation which you consider stable and independently useful.

Sorry, didn't notice that :(. Luckily a slight change removes all abi
modification part.

1) Create class _ScannerBase to make _Scanner pithier.
2) Make _Compiler and _Scanner `_FwdIter independent`. We store the
input regex string in basic_regex as a basic_string; but when
compiling it, const _CharT* is used.
3) Avoid using std::map, std::set and std::queue to reduce compile time.

Booted and tested with -m64 and -m32 respectively, and check-debug; by
the way, along with previous patch in the mail "[Patch] Regex bracket
matcher cache optimization".

Thanks!
