e5456dea52 Although probably not necessary, guard against a potential assertion by 
using isNullValue() instead of getZExtValue() == 0.

3a7689fe22 Use isUnitValue() instead of getZExtValue() == 1 which will prevent an 
assert if the ConstantInt's value is large.

Reid Spencer
2ce72a4bd8 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.

APInt constructor.

327ae8b712 Use APInt conversion to string so the result is correct regardless of the 
bit width of the ConstantInt being converted.

5790924b21 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.

30eac3e0b1 The 64-bit constructor for ConstantInt changes from int64_t to uint64_t. 
This caused a warning for construction with -1. Avoid the warning by using
-1ULL instead.

125af87a25 Use a simpler constructor when constructing ConstantInt. Also, replace 
verbose code to sext/trunc or zext/trunc and APInt with new methods on
that class.

b4e877c488 Drop the ConstantInt(const Type&, const APInt&) constructor. It is 
redundant and more verbose than the ConstantInt(const APInt&) constructor.
