bc687c27d7 delete stores to allocas with one use. This is a trivial form of DSE which

c32e0fedab For PR1113: 
Increment the counter after the second use, not after the first use. This
fixes PR1113.

Also, rename some classes for simplicity and to more naturally be
reminscient of LLVM 1.9. This in preparation for additional classes that
will provide a scaled down model of the LLVM 1.9 IR.

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! :)

6026cbf165 Terminology change: drop 'integral' completely. Now we just have integer, 
which includes i1.  Change the semantics of the various instructions to
support i1 where they didn't before: for example, it is now legal [though
not terribly useful, as it is the same as xor] to add two i1 values.

a5cbe5f4e5 Reorganize things a bit in preparation for rewrite. Although this looks 
like a lot, its really only two changes:

1. Move stuff that should be private to .y out of the .h file.
2. Make all semantic values pointers.

This cleans up the silly destroy methods and changes them to delete. It
also moves the TypeInfo and ValueInfo classes into the .y where we can
modify them more readily because they have no clients any more.

This shouldn't result in any functional changes in llvm-upgrade.
