Improve APInt interface:
...
1. Add unsigned and signed versions of methods so a "bool" argument doesn't
need to be passed in.
2. Make the various getMin/getMax functions all be inline since they are
so simple.
3. Simplify sdiv and srem code.

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.

1. Make sure all delete operators of arrays use the array form of delete.
...
2. Rewrite operator=(const APInt& RHS) to allow the RHS to be a different
bit width than the LHS. This makes it possible to use APInt as the key
of a DenseMap, as needed for the IntConstants map in Constants.cpp
3. Fix operator=(uint64_t) to clear unused bits in case the client assigns
a value that has more bits than the APInt allows.
4. Assert that bit widths are equal in operator==
5. Revise getHashValue() to put the bit width in the low order six bits.
This should help to make i1 0, i2 0, ... i64 0 all distinct in the
IntConstants DenseMap.

2. Make internal functions that return a carry/borrow return bool instead
of uint64_t because the carry/borrow can only be in range [0,1].
3. Assert that the pointers to KnuthDiv are all different so that the
result and operands can't overlap.
4. Add debug output to KnuthDiv function.
5. Fix a problem with KnuthDiv by separating the b's complement operation
from the subtraction borrow operation. This fixes a wide range of
division problems, but alas, not all of them.

1. Ensure pVal is set to 0 in each constructor.
2. Fix roundToDouble to make correct calculations and not read beyond the
end of allocated memory.
3. Implement Knuth's "classical algorithm" for division from scratch and
eliminate buffer overflows and uninitialized mememory reads. Document
it properly too.
4. Implement a wrapper function for KnuthDiv which handles the 64-bit to
32-bit conversion and back. It also implement short division for the
n == 1 case that Knuth's algorithm can't handle.
5. Simplify the logic of udiv and urem a little, make them exit early, and
have them use the "divide" wrapper function to perform the division
or remainder operation.
6. Move the toString function to the end of the file, closer to where
the division functions are located.
Note: division is still broken for some > 64 bit values, but at least it
doesn't crash any more.

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.

...
- 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.

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.

From Dan Gohman:
...
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.
