APInt: update asserts for base-36
...
Hexatridecimal was added in r139695.
And fix the unittest that now triggers the assert.

Fix APInt::operator*= so that it computes the correct result for large integers where there is unsigned overflow. Fix APFloat::toString so that it doesn't depend on the incorrect behavior in common cases (and computes the correct result in some rare cases). Fixes PR11086.

The signed version of our "magic number" computation for the integer approximation
...
of a constant had a minor typo introduced when copying it from the book, which
caused it to favor negative approximations over positive approximations in many
cases. Positive approximations require fewer operations beyond the multiplication.
In the case of division by 3, we still generate code that is a single instruction
larger than GCC's code.
