John McCall 75f9498a7c The conditional needs to be pushed before the branch. Make the test less
trivial to check this.  Adjust for style.

John McCall f7dcf320a7 An operator new with an empty exception specifier returns null on a bad
allocation and therefore requires a null-check.  We were doing that, but
we weren't treating the new-initializer as being conditionally executed,
which means it was possible to get ill-formed IR as in PR9298.

John McCall 1b93f1ba9f Tame an assert; the scope depth of a jump destination does not
necessarily enclose the innermost normal cleanup depth, because
the top of the jump scope stack might be an EH cleanup or EH scope.
Fixes PR9303.

John McCall f256eb54a2 Fix some obvious bugs in the conditional-cleanup code and then make the
dtor cleanup use it.

John McCall 7f9c92a9a0 When emitting a new-expression inside a conditional expression,
the cleanup might not be dominated by the allocation code.
In this case, we have to store aside all the delete arguments
in case we need them later.  There's room for optimization here
in cases where we end up not actually needing the cleanup in
different branches (or being able to pop it after the
initialization code).

Also make sure we only call this operator delete along the path
where we actually allocated something.

Fixes rdar://problem/8439196.

John McCall 824c2f537c Implement the EH cleanup to call 'operator delete' if a new-expression throws
(but not if destructors associated with the full-expression throw).

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Anders Carlsson afd1edb52e When an exception needs to be freed by calling __cxa_exception_free, make sure to stash away the exception pointer somewhere.
This fixes an "Instruction does not dominate all uses!" verification error when compiling TableGen.
