Several improvements to template argument deduction:
  - Once we have deduced template arguments for a class template partial
    specialization, we use exactly those template arguments for instantiating
    the definition of the class template partial specialization.
  - Added template argument deduction for non-type template parameters.
  - Added template argument deduction for dependently-sized array types.

With these changes, we can now implement, e.g., the remove_reference
type trait. Also, Daniel's Ackermann template metaprogram now compiles
properly.

Fixed a test case which I am to blame for making it
not runaable.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72695 91177308-0d34-0410-b5e6-96231b3b80d8

Update test case.

Fix a bug in hasEmptyExceptionSpec. (Thanks Sebastian for noticing).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72691 91177308-0d34-0410-b5e6-96231b3b80d8

PR4289: Make sure "&func" has the right LLVM type when "func" is a
K&R-style definition.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72690 91177308-0d34-0410-b5e6-96231b3b80d8

PR4287: allow a variadic prototype to make a subsequent K&R style
definition variadic.  I'm not completely sure it's legal, but the
standard can be interpreted as making it legal, and gcc seems to think
it's legal, so I didn't add an extension warning.

Simplify run line.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72687 91177308-0d34-0410-b5e6-96231b3b80d8

PR4283: Don't truncate multibyte character constants in the
preprocessor.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72686 91177308-0d34-0410-b5e6-96231b3b80d8

Disable type merging with gc attributes.  This has a number of nasty
properties at the moment:

1. It allows stuff like "__strong id x; __weak id x;".

2. For constructs like "__strong id x; id x;", subsequent references to
x lose the objc_gc attribute.

3. This incorrectly allows merges involving the address_space attribute.

4. Constructs like "id x; /* some code using x */ __weak id x;" don't
apply the objc_gc attribute consistently to all uses of x.

The first three can probably be fixed relatively easily; the fourth
would be extremely difficult to fix.

Use a reference to modify the DeclIDs map.

After spending 15 minutes trying to figure out why this was crashing, I realized it was a bug in the test case :)

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72680 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a thinko.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72679 91177308-0d34-0410-b5e6-96231b3b80d8

Check for null correctly for new expressions.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72678 91177308-0d34-0410-b5e6-96231b3b80d8

Improve irgen of 'new' further.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72677 91177308-0d34-0410-b5e6-96231b3b80d8

...and aggregate POD types.

Support for complex types.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72675 91177308-0d34-0410-b5e6-96231b3b80d8

Better support for scalar POD types in 'new' expressions.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72674 91177308-0d34-0410-b5e6-96231b3b80d8

Make sure to copy back arguments that can be changed by FindAllocationOverload. This fixes placement new. (Sebastian, please review).

Very basic irgen support for new expressions.
