process. The only optimization we did so far is to avoid creating a
PHI node, then immediately destroying it in the common case where the
callee has one return statement. Instead, we just don't create the return
value. This has no noticable performance impact, but paves the way for
future improvements.

PHI node entries for unwind instructions just like for call instructions which
became invokes! This fixes PR57, tested by
Inline/2003-10-26-InlineInvokeExceptionDestPhi.ll

break dominance relationships, and is otherwise bad. This fixes bug:
Inline/2003-10-13-AllocaDominanceProblem.ll. This also fixes miscompilation
of 3 176.gcc source files (reload1.c, global.c, flow.c)

Running the inliner on 252.eon used to take 48.4763s, now it takes 14.4148s.
In release mode, it went from taking 25.8741s to taking 11.5712s.
This also fixes a FIXME.

... by making sure to update PHI nodes to take into consideration the
extra edges we get if we inline a call instruction through an invoke.
