SI-7710 fix memory performance of RegexParsers in jdk7u6+

Starting with 1.7.0_06 [1], String.substring no longer reuses the internal
char array of the String but make a copy instead. Since we call
subSequence twice for *every* input character, this results in horrible
parse performance and GC.

With the benchmark from the (duplicate) ticket SI-8542, I get:

BEFORE:
    parseAll(new StringReader(String))
    For 100 items: 49 ms
    For 500 items: 97 ms
    For 1000 items: 155 ms
    For 5000 items: 113 ms
    For 10000 items: 188 ms
    For 50000 items: 1437 ms
    ===
    parseAll(String)
    For 100 items: 4 ms
    For 500 items: 67 ms
    For 1000 items: 372 ms
    For 5000 items: 5693 ms
    For 10000 items: 23126 ms
    For 50000 items: 657665 ms

AFTER:
    parseAll(new StringReader(String))
    For 100 items: 43 ms
    For 500 items: 118 ms
    For 1000 items: 217 ms
    For 5000 items: 192 ms
    For 10000 items: 196 ms
    For 50000 items: 1424 ms
    ===
    parseAll(String)
    For 100 items: 2 ms
    For 500 items: 8 ms
    For 1000 items: 16 ms
    For 5000 items: 79 ms
    For 10000 items: 161 ms
    For 50000 items: 636 ms
