When outputing a non-lazy pointer for a stub, we may need to fill in the value
for the NLP because the object it's pointing to may be internal to the file.
This seems counter-intuitive, but bear with me. When we place the LSDA into the
TEXT section, the type info pointers need to be indirect and pc-rel. We
accomplish this by using NLPs. However, sometimes the types are local to the
file. GCC gets around this by not using a NLP in this case, but a "regular"
indirection like this:
GCC_except_tbl:
.long Lfoo-.
__ZTIA: @ This is local
...
Lfoo:
.long __ZTIA
LLVM prefers NLPs on Darwin. In fact, it's more optimal for load performance to
use them.

Add a couple more heuristics to neuter machine cse some more.
1. Be careful with cse "cheap" expressions. e.g. constant materialization. Only cse them when the common expression is local or in a direct predecessor. We don't want cse of cheap instruction causing other expressions to be spilled.
2. Watch out for the case where the expression doesn't itself uses a virtual register. e.g. lea of frame object. If the common expression itself is used by copies (common for passing addresses to function calls), don't perform the cse. Since these expressions do not use a register, it creates a live range but doesn't close any, we want to be very careful with increasing register pressure.
Note these are heuristics so machine cse doesn't make register allocator unhappy. Once we have proper live range splitting and re-materialization support in place, these should be evaluated again.
Now machine cse is almost always a win on llvm nightly tests on x86 and x86_64.

the encoding of non-lazy pointers to add the symbol to the non-lazy pointer
