bd616b69f7 XFAIL the test I added with vg_leak, apparently it is the first and only llc 
-filetype=obj test, and -filetype=obj leaks a few objects. Added a FIXME, we
need to sort out the ownership model for the various MC objects.

0ebf356ddf Get rid of the bit twiddling to read / set OpActions and ValueTypeActions. The small saving in memory isn't worth the increase in runtime and code complexity in my opinion.

7d4f25904d Fix an embarrassing runtime regression for RegAllocFast. 
This loop is quadratic in the capacity for a DenseMap:

  while(!map.empty())
    map.erase(map.begin());

Instead we now do a normal begin() - end() iteration followed by map.clear().
That also has the nice sideeffect of shrinking the map capacity on demand.

18e05b4692 Fix complete badness in bugpoint's IsARMArchitecture() function. 
The revision history for this function is interesting, with multiple layers of
wrongness being introduced one at a time.

This fixes a weird issue where bugpoint -run-llc would suddenly exit 13 half way
through isolating a miscompilation.

33ab0b1568 Replace the core comparison login in merge functions. We can now merge 
vector<>::push_back() in:

  int foo(vector<int> &a, vector<unsigned> &b) {
    a.push_back(10);
    b.push_back(11);
  }

to two calls to the same push_back function, or fold away the two copies of
push_back() in:

  struct T { int; };
  struct S { char; };
  vector<T*> t;
  vector<S*> s;
  void f(T *x) { t.push_back(x); }
  void g(S *x) { s.push_back(x); }

but leave f() and g() separate, since they refer to two different global
variables.
