c5a25532c7 Fix another really nasty regression that Anshu pointed out. In cases where 
dangling constant users were removed from a function, causing it to be dead,
we never removed the call graph edge from the external node to the function.

In most cases, this didn't cause a problem (by luck).  This should definitely
go into 1.3

bbf11b1e1d Changes commited for Nate Begeman: 
Use a PowerPC specific prolog epilog inserter to control where spilled
callee save regs are placed on the stack.
Get rid of implicit return address stack slot, save return address reg
(LR) in appropriate slot
Improve code generated for functions that don't have calls or access
globals


Note from Chris: PowerPCPEI will eventually be eliminated, once the
functionality is merged into CodeGen/PrologEpilogInserter.cpp

3f4d9ffde5 FindGlobalNamed used to take 2.92s out of 8.39s running a profile build of 
gccld -disable-opt on 252.eon.

This patch deletes it and replaces it with a map.  The proper fix for this
is to fix PR411, but this will do in the short term.

gccld on eon now takes 5.51s, which is 50% faster than before this patch. :)

4a2f261fab Concisify some code 
Do not call FindGlobalNamed when we know we will ignore the result (because
we are not going to link a static symbol anyway).  This speeds up
gccld -disable-opt on 252.eon from 8.63s to 8.39s.

lookups it does.  This shaves another 5% off of bcreading 252.eon.  Note that
the proper solution to this problem is to fix PR411, but that will have to
wait until later.
