well as a vector of constant*'s. It turns out that this is more efficient
and all of the clients want to do that, so we should cater to them.

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)

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.

(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.

This method is linear time in the size of the basic block, which is very
bad for large basic blocks. On the Assembler/2004-09-29-VerifierIsReallySlow.llx
testcase, the verifier changes from taking 50s to 0.23s with this patch.

from ModulePass. Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.
Also, fix some undefined behavior, expecting | on booleans to evaluate
left-to-right.

source module is one of the dependent libraries, it is removed from the
list.

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

error message, print out:
llvm-link: error linking in 'g.2.rbc': Global Variable Collision on
' %struct.D_Reduction* %d_reduction_10_gram' - External linkage globals have

That's a bit more concise, huh?

Ouch! Changes in the lazy initialization code caused each incorporated
function to reprocess the entire function on every lookup of a value's
slot number. This caused a horrible slowdown in all functions. This
fix made llvm-dis go from "longer than I care to wait" (minutes) on a large
test case to 0.53 seconds.
