were still inlining self-recursive functions into other functions.

Inlining a recursive function into itself has the potential to
reduce recursion depth by a factor of 2, inlining a recursive
function into something else reduces recursion depth by exactly 
1.  Since inlining a recursive function into something else is a
weird form of loop peeling, turn this off.

The deleted testcase was added by Dale in r62107, since then
we're leaning towards not inlining recursive stuff ever.  In any
case, if we like inlining recursive stuff, it should be done 
within the recursive function itself to get the algorithm 
recursion depth win.

indexes could be of a different value type. Or not even using the same SDNode
for the constant (weird, I know). Compare the actual values instead of the
pointers.

instruction selection is done; it's confusing to see parts of it printed,
while other parts are omitted, along the way.

slots.

We used to spill those dirty CSRs after the call, and the stack slots would be
wrong when arriving at the landing pad.

of different register classes. e.g.

  %reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3

Where %reg1048 is a GR32 register. This is not impossible to handle, but it is
pretty hard and very rare.

This should unbreak the dragonegg builder.
