074b8a080e Make APInt a little more friendly to its users: 
* Add support for + and - of a uint64_t.
  * Make trunc/sext/zext return *this so it can be chained with other ops
  * Add smin, smax, umin, umax functions for getting min/max values.

9875fc1500 Implement support for aribrary precision integers by creating two new 
tokens: ESAPINTVAL and EUAPINTVAL and adding an APInt* as a semantic value.
This allows us to extend the definition of an integer constant to allow
arbitrary precision integer constant values.

31acef50ad Implement countLeadingOnes() and getMinSignedBits(). This helps to minimize 
the bit width of negative numbers by computing the minimum bit width for a
negative value. E.g. 0x1800000000000000 could be just 0x8000000000000000
