2. Implement toString for power-of-2 radix without using divide and always
   printing full words. This allows hex/binary to look at the bit
   respresentation of the APInt as well as avoid bugs in divide.

2. Teach slt about signedness.
3. Teach roundToDouble to properly sign extend.

   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).

2. Consolidate memory allocation into just two inline functions.
3. Convert "unsigned" to uint32_t to gaurantee its size.
4. Eliminate magic constants and replace with symbolic equivalent.
5. Improve code documentation slightly.
6. Simplify the logical operator code because bitwidths must be the same.
7. Fix indentation per coding standards.
8. Use exit-early style to reduce indentation in several functions.

llvm-svn: 34389

Fix line breaks and 80 cols violation.
Simplify operator^= since bitwidths must be the same.

Fix bugs in countLeadingZeros and countTrailingZeros.

- 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.

- Added a virtual method to return target specific reserved registers, e.g. SP.

_test2:
        li r2, 0
        lis r3, 1
        std r2, 9024(r3)
        blr

instead of:

_test2:
        lis r2, 1
        li r3, 0
        ori r2, r2, 9024
        std r3, 0(r2)

Implement support for ppc64 as well, allowing it to produce better code.
