4ed1082683 Simplify the handling of physreg defs and uses in RegAllocFast.
This adds extra security against using clobbered physregs, and it adds kill
markers to physreg uses.

c0c32ae5c2 Don't use isBarrier for the PowerPC sync instruction. isBarrier is for
control barriers, not memory ordering barriers.

9cc1c18b7b Use regular PassManager instead of FunctionPassManager in opt, since it
isn't doing lazy streaming. This also fixes a missing doFinalization call.

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.

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.

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.
