Dan Gohman 24a492683c Revert r117582, which reverted r77396. Searching PATH for a string 
which contains slashes is inconsistent with the meaning of PATH on
Unix-type platforms, and pretty surprising.

If the user has given a specific path to execute and we can't
execute it, we should fail and say why.  (Apparently the new
posix_spawn code doesn't always say why, but that's a separate
issue.)

This doesn't usually matter, because the other heuristics usually
succeed regardless, but it's good to keep the register use
bookkeeping consistent.

Dan Gohman f53458f693 When an MDNode changes to become identical to another MDNode, 
delete the MDNode that changed, rather than the other MDNode.
This is less work, because it doesn't require the changed node
to be re-inserted into the uniquing map and it doesn't require
the is-function-local flag to be recomputed. Also, it avoids
trouble when the existing node is part of a complicated
data structure.
