third patch

I like the last option, and renamed the flag to XCL_HASPROP. This change also
revealed some minor issues. I hope this patch is close to the final version,
since it has grown a bit large. Although I have several folloup ideas, such as
improving the auto-possessifying based on this flag, and range detection in JIT
can also be improved. I was also wondering, when too many starting bits are set
(>75%) by pcre_study, the starting character check might become a burden not a
gain.
