involving substitution of deduced template arguments into a class
template partial specialization or function template, or when
substituting explicitly-specific template arguments into a function
template. We now print the actual deduced argument bindings so the
user can see what got deduced.

This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

dyn_cast) invocations for C++ and Objective-C types, declarations,
expressions, and statements. The statistics will be printed when
-print-stats is provided to Clang -cc1, with results such as:

277073 clang - Number of checks for C++ declaration nodes
 13311 clang - Number of checks for C++ expression nodes
    18 clang - Number of checks for C++ statement nodes
174182 clang - Number of checks for C++ type nodes
 92300 clang - Number of checks for Objective-C declaration nodes
  9800 clang - Number of checks for Objective-C expression nodes
     7 clang - Number of checks for Objective-C statement nodes
 65733 clang - Number of checks for Objective-C type nodes

The statistics are only gathered when NDEBUG is not defined, since
they introduce potentially-expensive operations into very low-level
routines (isa).

Handle default arguments when calling copy constructors for bases or members when synthesizing a copy constructor. Fixes PR6628.

Flip the switch and use the new vtable layout code for everything. I've verified that this passes a self-host but I'll let the bots self host as well before removing the now dead code.

BumpPtrAllocator rather than using up slots in the ASTContext's
cache. Now that we do this, we don't have to worry about destroying
dependent diagnostics when destroying a DependentStoredDeclsMap.

cache of PartialDiagnostic::Storage objects into an allocator within
the ASTContext. This eliminates a significant amount of malloc
traffic, for a 10% performance improvement in -fsyntax-only wall-clock
time with 403.gcc's combine.c.

Also, eliminate the RequireNonAbstractType hack I put in earlier,
which was but a symptom of this larger problem.

When collecting virtual bases it's very important to use the canonical type of the base class. Otherwise, we might add the same virtual base class twice if the virtual base is an instantiated template. Fixes PR6251.

Fix a nasty bug in the virtual base computation which would lead to us initializing virtual bases in the wrong order.

This patch moves some methods from QualType to Type and changes the users to
use -> instead of .

More vtable work - it's not possible to use the new vtable code for everything by setting a flag inside CGVtable.cpp. My plan is to run some tests and bootstrap and once that's done flip the bit.

llvm-svn: 99804

Only add thunks for the most derived class. This fixes some link errors I was seeing in files generated by the vtable tester utility.

Flip the switch to always get vtables from the VTT when necessary, I've verified that clang bootstraps with this.

Make sure to sort the vtable thunks by their vtable index :) With this we now pass the test from http://www.codesourcery.com/public/cxx-abi/abi-examples.html#vtable-ctor successfully.
