David Faure a8ae8e3130 QDateTime::fromString(): improve performance by 33% 
getMaximum() and getMinimum(), called during parsing, create new
QDateTime instances, which on Linux end up calling mktime().
Making these static (for the common case of LocalTime spec)
improves performance dramatically, when parsing several date/times.

tests/benchmarks/corelib/tools/qdatetime/ (after fixing it to
actually parse a valid date/time) says:
 RESULT : tst_QDateTime::fromString():
-     36,742,060 instruction reads per iteration (total: 36,742,060, iterations: 1)
+     24,230,060 instruction reads per iteration (total: 24,230,060, iterations: 1)
