Split the init.trampoline intrinsic, which currently combines GCC's
init.trampoline and adjust.trampoline intrinsics, into two intrinsics
like in GCC. While having one combined intrinsic is tempting, it is
not natural because typically the trampoline initialization needs to
be done in one function, and the result of adjust trampoline is needed
in a different (nested) function. To get around this llvm-gcc hacks the
nested function lowering code to insert an additional parent variable
holding the adjust.trampoline result that can be accessed from the child
function. Dragonegg doesn't have the luxury of tweaking GCC code, so it
stored the result of adjust.trampoline in the memory GCC set aside for
the trampoline itself (this is always available in the child function),
and set up some new memory (using an alloca) to hold the trampoline.
Unfortunately this breaks Go which allocates trampoline memory on the
heap and wants to use it even after the parent has exited (!). Rather
than doing even more hacks to get Go working, it seemed best to just use
two intrinsics like in GCC. Patch mostly by Sanjoy Das.

not equal the number of predecessors. E.g., two or more landingpad instructions

Enable SCEV-based unrolling by default.
This changes loop unrolling to use the same mechanism for trip count
computation as indvars. This is a stronger check that tends to unroll
more loops. A very common side-effect is that many single iteration
loops will be removed sooner. The real goal was simply to remove
dependence on canonical IVs.

Perform the upgrading of the old EH to the new EH in a more sane manner.
Perform the upgrading in steps.
* First, create a map of the invokes to the EH intrinsics.
* Next, take that mapping and determine if the invoke's unwind destination has a
single predecessor. If not, then create a new empty block to hold the new
landingpad instruction.
* Create a landingpad instruction into the uwnind destination. Fill it with the
values from the old selector. Map the old intrinsic calls to the new
landingpad values (there may be multiple landingpad instructions per instrinic
call pairs).
* Go through the old intrinsic calls, create a PHI node when necessary, and then
replace their values with the new values from the landingpad instructions.
