Hi,
This patch adds a support of conditional store sinking for cases with
multiple data references in then and else basic blocks. The
correctness of the transformation is checked by verifying that there
are no read-after-write and write-after-write dependencies.

IIRC, if this patch does not go in 4.6, then we have to write some
special and ugly GDB code to work around the debuginfo generated by 4.6.
I would much prefer it if there was no need to write this code.

update to fixup virtual operands isn't a good idea if we incrementally
walk through all sinking candidates. Fixed by manually updating virtual

In this case, fold is turning one() = 0 into (one(), true) because the
