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. :)

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 :)

exponential behavior (bork!). This patch processes stuff with an

Change Type::isAbstract to have better comments, a more correct name
...
(PromoteAbstractToConcrete), and to use a set to avoid recomputation.
In particular, this set eliminates the potentially exponential cases
from this little recursive algorithm.
On a particularly nasty testcase, llvm-dis on the .bc file went from 34
minutes (which is when I killed it, it still hadn't finished) to 0.57s.
Remember kids, exponential algorithms are bad.
