836692dd8a delete stores to allocas with one use. This is a trivial form of DSE which 
often kicks in for ?: expressions.

42a7551725 rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)
