f734ea21a3 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.

immediately after 'stay informed' and right before 'code reviews'.

f99a0ac0dc 1. Fix some indentation and variable names in the get{Min,Max}Value methods. 
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.

a932e3f799 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).

af0e956cef 1. Remove dead code (lshift function). 
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.
