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.

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.

Fix a bug in RoundDoubleToAPInt where it would force the size to 64 bits
