Change the Opcode enum for PHI nodes from "Instruction::PHINode" to "Instruction::PHI" to be more consistent with the other instructions.

Only transform call sites in a setjmp'ing function which are reachable from
the setjmp.  If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.

This dramatically reduces the number of invoke instructions created in some
large testcases.

of callees between executions.

On eon, in release mode, this changes the inliner from taking 11.5712s
to taking 2.2066s.  In debug mode, it went from taking 14.4148s to
taking 7.0745s.  In release mode, this is a 24.7% speedup of gccas, in
debug mode, it's a total speedup of 11.7%.

This also makes it slightly more aggressive.  This could be because we
are not judging the size of the functions quite as accurately as before.
When we start looking at the performance of the generated code, this can
be investigated further.

Thanks to brg for tracking down the problem so precisely!

in it being both shorter and more effective.  It no longer depends on the
callgraph, so one FIXME has been fixed.

Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead.  In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.

Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

This makes it more efficient: it doesn't have to scan the whole program, so
it performs work proportional to the number of malloc/free calls in the
program, not the size of the program.

  * Separate the policy decisions into a derived class [InlineSimple]
  * Move the inlining mechanics into a base class [Inliner]
  * Change the inliner to be an SCCPass, making it more structured and
    eventually pipelinable with other SCC passes
