mode with optimizations and the built llvm passes make check.

fix an IPSCCP bug I introduced when I changed IPSCCP to start working on 2009-11-03T19:24:51ZChris Lattnersabre@nondot.org2009-11-03T19:24:51Zurn:sha1:2396cc37ae6f29693b0984e0d9129487a4e3830c
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.

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.
