f8380b953a If we are trying to create a ConstantExpr cast that is really a GEP to the 
first element of an array, return a GEP instead of a cast.  This allows us
to transparently fold this:

int* getelementptr (int* cast ([100 x int]* %Gbody to int*), int 40)

into this:

int* getelementptr ([100 x int]* %Gbody, int 0, int 40)

50e55bcdb0 Unfortunately the fix for the previous bug introduced the previous 
exponential behavior (bork!).  This patch processes stuff with an
explicit SCC finder, allowing the algorithm to be more clear,
efficient, and also (as a bonus) correct!  This gets us back to taking
0.6s to disassemble my horrible .bc file that previously took something
> 30 mins.

c2563bf614 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.

da5c635143 Don't use DominatorSet::dominates for intra-block instruction dom checks. 
This method is linear time in the size of the basic block, which is very

This patch deletes it and replaces it with a map.  The proper fix for this
