also fixes PR8250.

Fix zeroExtend and signExtend to support empty sets, and to return the smallest
possible result set which contains the extension of each element in their
inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10)
which contains 63446 members.

 - remove ashr which never worked.
 - fix lshr and shl and add tests.
 - remove dead function "intersect1Wrapped".
 - add a new sub method to subtract ranges, with test.

this is still minimal on purpose, but I plan to migrate the ugly
hack under #ifdef DEBUG_CAST_OPERATORS into this file

TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.

 - As best I can tell, we have eliminated all the code which used to require a
   larger buffer size.

TypeBuilder was using a local static variable to cache its result. This made it
ignore changes in its LLVMContext argument and always return a type constructed
from the argument to the first call.

the former will print out the contents of the constant range that failed.

means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

 - This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)

ConstantRange doesn't have an std::ostream inserter anymore.
