36184ed4cd Fix a problem where shifting by 64-bits leads to incorrect results on PPC 
but not on X86 becuase shift by word size is "undefined".

cae5754619 Prefer non-virtual calls to ConstantInt::isZero over virtual calls to 
Constant::isNullValue() in situations where it is possible.

34da0ac28f Add a non-virtual test for zero, isZero, and rename isUnitValue isOne. 
These will be used in upcoming patches to avoid virtual function call when
the client knows it is a ConstantInt.

a3507ebd33 Although probably not necessary, guard against a potential assertion by 
using isNullValue() instead of getZExtValue() == 0.

4da0451821 Use isUnitValue() instead of getZExtValue() == 1 which will prevent an 
assert if the ConstantInt's value is large.

Reid Spencer
37eeaa729b Add an isUnitValue method for comparison against 1. This just follows a 
common pattern with isNullValue, isAllOnesValue, etc. It also helps to
prevent things like getZExtValue() == 1, which could assert for large
bitwidths.

0d54b7df4f Use the APInt versions of the bit-wise conversions of float/double to int 
and back. While this is not strictly necessary, it does pave the way for
future changes in casting. It should now be possible to improve vector
casting to deal with un-equal fp/int sizes.

62aa905595 The 64-bit constructor for ConstantInt changes from int64_t to uint64_t.
