39f398b50d Fix bug raising allocations whose call sites were invoke instructions. 
Thanks to brg for tracking down the problem so precisely!

ec6d7a6df3 This is effectively a complete rewrite of the globaldce algorithm, resulting 
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.

8ef1b88aef Change the RaiseAllocations pass to be a Pass instead of a BasicBlock pass. 
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.

d075cc282b Heavily refactor code: 
* 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
