Partial fix for PR1502: If a EH register is needed in a successor of landing pad, add it as livein to all the blocks in the paths between the landing pad and the specified block.

Use cached information that has already been computed to make clean() simpler and faster.  This is a small speedup on most cases.

This saves many lines of code duplication.  No functionality change.

2. When calculating ANTIC_IN, only iterate the changed blocks.  For most average
inputs this is a small speedup, but for cases with unusual CFGs, this can be a significant win.

2. Fix default URL for SVN access.
3. Fix paths to accommodate "trunk" when checking out from SVN.

Use a better determinator for identifying constant array initializers that
are or are not zero terminated and generate code appropriately.
