53a673b3ed 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.

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.

the bit width of negative numbers by computing the minimum bit width for a

c8cc0f997e For PR1205: 
Implement the first step towards arbitrary precision integer support in
LLVM. The APInt class provides arbitrary precision arithmetic and value
representation. This patch changes ConstantInt to use APInt as its value
representation without supporting bit widths > 64 yet. That change will
come after ConstantFolding handles bit widths > 64 bits.

50be7cd320 Rework GlobalValue::removeDeadConstantUsers to always remove dead constant 
exprs hanging off a global, even if the global is not otherwise dead.  This

constantexpr that made it appear that the address of the function was taken.

a4ab1c36d2 Fix clearUnusedBits to not depend on "undefined behavior" of >> operator 
when the bit size is equal to the word size. This happens to work out okay
on x86, but might not on other platforms. The change just detects when
there are no bits to clear (because BitWidth is a multiple of the word size)
and returns early.

Also, move some comments from .cpp file into header.

78e1ec0122 Implement support for non-standard integer bit widths of any size. The 
rules alignment is to pick the alignment that corresponds to the smallest
specified alignment that is larger than the bit width of the type or the
largest specified integer alignment if none are larger than the bitwidth
of the type. For the byte size, the size returned is the next larger
multiple of the alignment for that type (using the above rule). This patch
also changes bit widths from "short" to "uint32_t" to ensure there are
enough bits to specify any bit width that LLVM can handle (currently 2^23);
16-bits isn't enough.

79d2fad9f5 1. "unsigned" -> "uint32_t" to gaurantee its bit width on all platforms. 
Size matters in this case.
2. Remove the unused whichByte private function, which was also broken.
3. Remove the non-const overload of the getWord function, getWord() is
   never used as an lvalue.
4. Rename some local variables for clarity (e.g. API -> Result).

8ac045a4b2 - Changes how function livein's are handled, they now have a start index of 0. 
- When coalescing a copy MI, if its destination is "dead", propagate the
  property to the source MI's destination if there are no intervening uses.
- Detect dead function live-in's and remove them.

d22266f456 Review changes: 
1. Function style changes.
2. 80-col violations.
3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
   corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
   converts to bool as comparison against 0. This allows the normal && and
   || operators to be used as if (X.getBoolValue() && Y.getBoolValue())

Note: this still doesn't function 100% yet. I'm working on the bugs now.
