Replace hard-coded lists of real-number types, and of arithmetic and logical operators I’m testing, with lists added to SwiftIntTypes.py, which becomes a bit of a misnomer.
Separate them into ones which only work on integer types, and those which also allow reals.
Do a double loop, over just the integers and then the reals as well.
Change the run line to allow importing StdlibUnittest with help from Dmitri, which I won't actually need until I do result type checking.
Approved by Dmitri.
Swift SVN r24029
for binary non-logical operators in _The Swift Programming Language_ "Basic Operators."
Until rdar://18695154 is fixed, + and - are disabled; this leaves 1440 tests.
