Do not lower malloc's to pass "sizeof" expressions like this:

ltmp_0_7 = malloc(((unsigned )(&(((signed char (*)[784])/*NULL*/0)[1u]))));
Instead, just emit the literal constant, like this:
ltmp_0_7 = malloc(784u);

Fix a nasty order of evaluation bug that Gabor Greif ran into. Here's an
...
explanation from IRC:
|sabre| I think it's an order of evaluation thing
|sabre| for me, the RHS of the assignment is evaluated first
|sabre| getTypeDescription checks to see if ConcreteTypeDescription[Ty] contains anything
|sabre| since it doesn't, it computes and returns the value
|sabre| this gets put into the map.
|sabre| For you, the LHS is evaluated first.
|sabre| Map[Ty] (aka ConcreteTypeDescriptions[Ty]) inserts an empty string into the map, returning a reference
|sabre| getTypeDesc then sees the empty string in the map
|sabre| and returns it
|sabre| bork :)

Fixed the following LSR bugs:
...
* Loop invariant code does not dominate the loop header, but rather
the end of the loop preheader.
* The base for a reduced GEP isn't a constant unless all of its
operands (preceding the induction variable) are constant.
* Allow induction variable elimination for the simple case after all.
Also made changes recommended by Chris for properly deleting
instructions.
