9a1f1c41b0 add new CC_X86_32_FastCall calling conv, which describes fastcall on win32. 
Factor out a CC_X86_32_Common convention, which is the part shared between
ccc, stdcall and fastcall

36f506df46 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.

14d26ed070 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.

edbe747bab 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
