When matching patterns that have a complex pattern as their root, make
...
sure to only run the complex pattern on nodes where the target opts in.
This patch only handles targets with one opcode specified so far, but
fixes 16 failures, only 34 left.

Mark the return address stack slot as mutable when moving the return address
...
during a tail call. A parameter might overwrite this stack slot during the tail
call.
The sequence during a tail call is:
1.) load return address to temp reg
2.) move parameters (might involve storing to return address stack slot)
3.) store return address to new location from temp reg
If the stack location is marked immutable CodeGen can colocate load (1) with the
store (3).
This fixes bug 6225.

result nodes correctly. Note that this includes a horrible hack

eliminating (parallel) from input patterns. That, in turn,
can't be done until we support writing multiple result patterns
for the X86and_flag and related multiple-result nodes.
