When checking for name collision between a tag and a previously defined namespace, the collision occured even when the tag was in a different nested scope.
...
Fix it by taking into account the scope when checking for namespace-tag name collisions.

return value as a whole in deadargelim is really not needed now that we simply

fix that next.

Make deadargelim a bit less smart, so it doesn't choke on nested structs as

return values that are still (partially) live. Instead of updating all uses of
a call instruction after removing some elements, it now just rebuilds the
original struct (With undef gaps where the unused values were) and leaves it to
instcombine to clean this up.
The added testcase still fails currently, but this is due to instcombine which
isn't good enough yet. I will fix that part next.

Make DeadArgElim keep liveness of the return value as a whole in addition to

only the liveness of partial return values (for functions returning a struct).
This is more explicit to prevent unwanted changes in the return value.
In particular, deadargelim now canonicalizes a function returning {i32} to
returning i32 and {} to void, if the struct returned is not used in its
entirety, but only the single element is used.

LegalizeTypes support for promotion of bswap.
...
In LegalizeDAG the value is zero-extended to
the new type before byte swapping. It doesn't
matter how the extension is done since the new
bits are shifted off anyway after the swap, so
extend by any old rubbish bits. This results
in the final assembler for the testcase being
one line shorter.
