Summary: When constructing an APSInt from a string, the constructor doesn't correctly truncate the bit width of the result if the passed in string was "0" (or any alternative way to express 0 like "-0" or "000"). Instead of 1 (which is the smallest allowed bit width) it returns an APSInt with a bit width of 5. The reason is that the constructor checks that it never truncates the result to the invalid bit width of 0, so when it calculates that storing a "0" doesn't require any bits it just keeps the original overestimated bit width (which happens to be 5). This patch just sets the bit width of the result to 1 if the required bit width is 0.
