ea859be53c Move ComputeMaskedBits, MaskedValueIsZero, and ComputeNumSignBits from
TargetLowering to SelectionDAG so that they have more convenient
access to the current DAG, in preparation for the ValueType routines
being changed from standalone functions to members of SelectionDAG for
the pre-legalize vector type changes.

0b2ce1fc19 std::set is really really terrible. Switch to SmallPtrSet to reduce compile time. For Duraid's example. The overall isel time is reduced from 0.6255 sec to 0.1876 sec.

82575d8ab1 Make a bunch of optimizations for compile time to GVNPRE, including smarter set unions, deferring blocks rather than computing maximal sets, and smarter use of sets. With these enhancements, the time to optimize 273.perlbmk goes from 5.3s to 2.7s.

61766cae0b Two changes:
1. Make SmallPtrSet::erase faster in the small case by replacing a memmove
    with a pointer copy.
 2. Fix a bug where the null terminator at the end of the array in the small
    case was not copied
