This fixes PR531, a crash when running the CBE on a bytecode file.
...
The problem is that Function::renameLocalSymbols is iterating through
the symbol table planes, occasionally calling setName to rename a value
(which used to do a symbol table remove/insert pair).
The problem is that if there is only a single value in a particular type
plane that the remove will nuke the symbol table plane, and the insert
will create and insert a new one. This hoses Function::renameLocalSymbols
because it has an iterator to the old plane, under the (very reasonable)
assumption that simply renaming a value won't cause the type plane to
disappear.
This patch fixes the bug by making the rename operation a single atomic
operation, which has a side effect of making the whole thing faster too. :)

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:

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.
