fc36a562ae reimplement multiple return value handling in IPSCCP, making it 
more aggressive an correct.  This survives building llvm in 64-bit
mode with optimizations and the built llvm passes make check.

5a1cd36019 Fix t2Int_eh_sjlj_setjmp. Immediate form of orr is a 32-bit instruction. So it should be 22 bytes instead of 20 bytes long.

2396cc37ae fix an IPSCCP bug I introduced when I changed IPSCCP to start working on 
functions that don't have local linkage.  Basically, we need to be more
careful about propagating argument information to functions whose results
we aren't tracking.  This fixes a miscompilation of 
LLVMCConfigurationEmitter.cpp when built with an llvm-gcc that has ipsccp
enabled.

12c8d5f5fe improve IPSCCP to be able to propagate the result of "!mayBeOverridden" 
function to calls of that function, regardless of whether it has local
linkage or has its address taken.  Not escaping should only affect 
whether we make an aggressive assumption about the arguments to a 
function, not whether we can track the result of it.
