[PATCH] D22991: AMDGPU: Change insertion point of si_mask_branch

Insert before the skip branch if one is created.
This is a somewhat more natural placement relative
to the skip branches, and makes it possible to implement
analyzeBranch for skip blocks.
    
The test changes are mostly due to a quirk where
the block label is not emitted if there is a terminator
that is not also a branch.
