If a constructor throws an exception we need to execute the destructors for all fully constructed members. Fixes ctor_dtor_count.cpp in the test suite.

- o32 cc must pass all arguments in A0...A3 and stack regardless
if its type (but respect the alignment).
- Store all variable arguments back to the caller stack.

params.  Don't insert addrof operations when matching against a pointer;
array/function conversions should take care of this for us, assuming the
argument type-checked in the first place.  Add a fixme where we seem to be
using a less-restrictive reference type than we should.

Fixes PR 6249.

only run for x86 with fastisel. I've found it being very effective in
eliminating some obvious dead code as result of formal parameter lowering
especially when tail call optimization eliminated the need for some of the loads
from fixed frame objects. It also shrinks a number of the tests. A couple of
tests no longer make sense and are now eliminated.

over to VarDecl::isThisDeclarationADefinition(), which handles
variables declared with linkage specifications better (among other
things). CMake 2.9 (from CVS) now builds with clang++ and is somewhat
functional.

Only append 'L' for internal variable declarations, not all declarations. (Found by the mangle checker, yay)

Also teach RegionStore::RetrieveVar() to handle 'static' pointers that are implicitly initialized to NULL.

Fix regression in RegionStore (from BasicStore) where static variables were not treated as being implicitly initialized to 0 (and instead were getting symbolicated).

Function-local metadata whose operands had been optimized to no longer refer to function-local IR were not getting written by BitcodeWriter; solution is for these metadata to be enumerated just like global metadata.

This time it's for real! I am going to hook this up in the frontends as well.

The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.

We need some experiments to determine if that is the right thing to do.
