bc687c27d7 delete stores to allocas with one use. This is a trivial form of DSE which 
often kicks in for ?: expressions.

c5e1611848 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! :)

716c76605c add a missing else. This caused globals to be printed as:

instead of:

b1b258fd1e fit to 80 cols. 
Remove now-extraneous checks for ptr->ptr bitcasts.

Fix PR1109 and Analysis/BasicAA/2007-01-13-BasePointerBadNoAlias.ll.  We
need to consider arbitrary sized objects when checking for nested GEP offsets.

99b79bdde3 Bye bye bool. AsmWriter doesn't generate it any more so AsmParser shouldn't 
read it any more. This is consistent with the new IR as well.

fa95bfe36f "Default context" blocks can occur after a non-default one. This meant 
that properties were being applied where they didn't belong. Fixes crash
in new MiBench testcase.

Also mark debugging code as such in #ifdef.
