Douglas Gregor c998409cce Remove an overly-eager assertion when replacing tokens with an
annotation token, because some of the tokens we're annotating might
not be in the set of cached tokens (we could have consumed them
unconditionally).

Also, move the tentative parsing from ParseTemplateTemplateArgument
into the one caller that needs it, improving recovery.

Douglas Gregor adee3e3b22 Template argument deduction for template template parameters. This
permits, among other things, ripping apart and reconstructing
templates via partial specialization:

  template<typename T> 
  struct DeepRemoveConst { typedef T type; };

  template<typename T>
  struct DeepRemoveConst<const T> {
    typedef typename DeepRemoveConst<T>::type type;
  };

  template<template<typename> class TT, typename T>
  struct DeepRemoveConst<TT<T> > {
    typedef TT<typename DeepRemoveConst<T>::type> type;
  };

Also, fix a longstanding thinko in the code handling partial ordering
of class template partial specializations. We were performing the
second deduction without clearing out the results of the first
deduction. It's amazing we got through so much code with such a
horrendous error :(

Dan Gohman 02b155427e Promote MergePotentialsElt and SameTailElt to be regular classes

Douglas Gregor 84d49a2085 Improve diagnostics when a default template argument does not match
with its corresponding template parameter. This can happen when we
performed some substitution into the default template argument and
what we had doesn't match any more, e.g.,

  template<int> struct A;
  template<typename T, template<T> class X = A> class B;

  B<long> b;

Previously, we'd emit a pretty but disembodied diagnostic showing how
the default argument didn't match the template parameter. The
diagnostic was good, but nothing tied it to the *use* of the default
argument in "B<long>". This commit fixes that.

Also, tweak the counting of active template instantiations to avoid
counting non-instantiation records, such as those we create for
(surprise!) checking default arguments, instantiating default
arguments, and performing substitutions as part of template argument
deduction.

Dan Gohman 64b5d0f468 Add support for tail duplication to BranchFolding, and extend
tail merging support to handle more cases.
 - Recognize several cases where tail merging is beneficial even when
   the tail size is smaller than the generic threshold.
 - Make use of MachineInstrDesc::isBarrier to help detect
   non-fallthrough blocks.
 - Check for and avoid disrupting fall-through edges in more cases.

Douglas Gregor eebed72fbb Move handling of template parameter packs out of the
template-type-parameter specific template argument checking code and
up to the template argument checking loop. In theory, this should make
variadic templates work better; in practice, they don't well enough
for us to care anyway (YET!), so this is mostly a re-organization to
simplify CheckTemplateArgument.

Jakob Stoklund Olesen 4f7fd3baeb Fix liveness calculation when splitting critical edges during PHI elimination.
- Edges are split before any phis are eliminated, so the code is SSA.

- Create a proper IR BasicBlock for the split edges.

- LiveVariables::addNewBlock now has same syntax as
  MachineDominatorTree::addNewBlock. Algorithm calculates predecessor live-out
  set rather than successor live-in set.

This feature still causes some miscompilations.

Douglas Gregor e62e6a0191 Before checking a template template argument against its corresponding
template template parameter, substitute any prior template arguments
into the template template parameter. This, for example, allows us to
properly check the template template argument for a class such as:

  template<typename T, template<T Value> class X> struct Foo;

The actual implementation of this feature was trivial; most of the
change is dedicated to giving decent diagnostics when this
substitution goes horribly wrong. We now get a note like:

  note: while substituting prior template arguments into template
      template parameter 'X' [with T = float]

As part of this change, enabled some very pedantic checking when
comparing template template parameter lists, which shook out a bug in
our overly-eager checking of default arguments of template template
parameters. We now perform only minimal checking of such default
arguments when they are initially parsed.

Devang Patel 5348515193 Do not eagerly set stop point for arguments. This misleads the debugger in identifying beginning of function body. Instead, create new location to attach with llvm.dbg.declare. This location is only used to find the context of the variable by the code generator, and it is not used to emit line number info.
