2372ccc111 Make getSTDIN return null if the standard input is empty, as the header file 
documentation implies and as its uses depend.

53424ad141 Allow the filename "-" to be a place holder for stdin. This allows directing 
stdin through llvm-ld and llvm-link.

df359c264e Small improvement: if a function doesn't access memory, we don't need to scan 
it for potentially undeading pointers.

c5f6a1f9d6 significantly speed up constant folding of calls (and thus all clients that use 
ConstantFoldInstruction on calls) by avoiding Value::getName().  getName() constructs
and returns an std::string, which does heap allocation stuff.  This slightly speeds up
instcombine.

de0e42d3c0 Speed up updateDFSNumbers with two observations: 
1. domtree is a tree, not a graph.  There is no need to avoid revisiting nodes with a set.
2. the worklist can contain the child iterator pointers so we don't get N^2 rescanning of children.

This speeds up updateDFSNumbers significantly, making it basically free.  On the testcase in PR1432,
this speeds up loopsimplify by another 3x, dropping it from the 12th most expensive pass to the to
the 30th. :)  It used to be #1.

3e089ae0b8 reimplement dfs number computation to be significantly faster. This speeds up 
natural loop canonicalization (which does many cfg xforms) by 4.3x, for 
example.  This also fixes a bug in postdom dfnumber computation.

a8d94f1315 - LiveInterval value#'s now have 3 components: def instruction #, 
kill instruction #, and source register number (iff the value# is defined by a
copy).
- Now def instruction # is set for every value#, not just for copy defined ones.
- Update some outdated code related inactive live ranges.
- Kill info not yet set. That's next patch.

cdbe4d3ebe Long double patch 8 of N: make it partially work in 
SSE mode (all but conversions <-> other FP types, I think):
>>Do not mark all-80-bit operations as "Requires[FPStack]"
(which really means "not SSE").
>>Refactor load-and-extend to facilitate this.
>>Update comments.
>>Handle long double in SSE when computing FP_REG_KILL.

w.r.t. #3, my patches last night happened to expose the bug, but this 
has been broken since Owen's r35839 patch to LoopSimplify.  The code
was subsequently moved over from LoopSimplify into Dominators, carrying
the latent bug.  Fun stuff.
