889cbe55b8 Fix a bug in the regexp caching. Also add a few more places to 
cache.  We now cache most of the places where Opera cache and
one or two where they do not cache for some reason.  Since
these optimizations aren't necessarily useful on real code we
may remove them if and when the Dromaeo website makes the
benchmarks harder to game.

3d36c712aa Use generated code to create sub strings. 
Added a stub to allocate and fill a string object with a substring from another string.

Use the rep movs instruction to copy the string data as it turned out to be the fastest way.

While preparing this I experimented with some SSE2 instructions, so the instructions movdqa and movdqu are still in the IA-32 assembler even though they are not used.

abbc6b9147 Don't use string slices when processing RexExp replace. 
String slices from RegExp replace results is now encoded in either one or two smis. Substrings are not used any more.

If the existing one smi encoding cannot hold the start/length information two smis are used the first having the negative length and the second having the start.

This is in preparation for removing string slices.
