​Fast routines to search and replace in strings (V2, on basis of SSE 4.2)

The units StrPosDefs and StrPos32 and/or StrPos64 contain functions that extend the functionality of system.pos and sysUtils.StringReplace and they may lead to significant performance improvements.

Functionality:
    • (repeated) location of substring in a string, (ANSIstring or String) with or without case sensitivity.
    • Replacement of a pattern by another pattern in a string or ANSIstring (one or all, with or without case sensitivity)
Platforms:
    • 32 and 64 bit windows.
Speed:
    • string replacement can be 7-10 times faster than standard.
    • String search gain: 2x in 32 bit mode (string); in 64 bit mode 6-7x faster with string, 35x faster with ANSIstring.

Note: the V2 files replace earlier files. StrPosDefs unit can be removed.
      the license condition have been changed.
