c34ebfbcfd Implement arbitrary integer constants through the use of APInt values. 
Positive, negative, and hexadecimal integer constants will now return an
APInt for values having > 64 bits of precision.

f231004a1c 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.

681dcd14e9 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

66ed1099ff Improve APInt interface: 
1. Add unsigned and signed versions of methods so a "bool" argument doesn't
   need to be passed in.
2. Make the various getMin/getMax functions all be inline since they are
   so simple.
3. Simplify sdiv and srem code.

a5c7472726 For PR1205: 
Implement review feedback:
1. Use new APInt::RoundDoubleToAPInt interface to specify the bit width so
   that we don't have to truncate or extend in constant folding.
2. Fix a pasteo in SDiv that prevented a check for overflow.
3. Fix the shift operators: undef happens when the shift amount is equal
   to the bitwidth.
