like this:

 def : Pat<(add ...),
           (FOOINST)>;

When fooinst only has a single implicit def (e.g. to R1).  This will be handled
as if written as (set R1, (FOOINST ...))

searches $PATH for its script argument, but dash, which /bin/sh
resolves to on some systems, does not.

temporary workaround for matching inc/dec on x86_64 to the correct instruction.
 - This hack will eventually be replaced with a robust mechanism for handling

always create a new jump table.  The intention was to avoid merging jump
tables in SelectionDAGBuilder, and to wait for the branch folding pass to
merge tables.  Unfortunately, the same getJumpTableIndex() method is also
used to merge tables in branch folding, so as a result of this change
branch tables are never merged.  Worse, the branch folding code is expecting
getJumpTableIndex to always return the index of an existing table, but with
this change, it never does so.  In at least some cases, e.g., pr6543, this
creates references to non-existent tables.

I've fixed the problem by adding a new createJumpTableIndex function, which
will always create a new table, and I've changed getJumpTableIndex to only
look at existing tables.
