Eli Friedman 48ddcf2cb5 Fix a CodeGen bug where we would skip zero-initialization for 
array new with a non-trivial constructor. Pointed out in PR13380.

John McCall f677a8e99e Convert the standard default-construction loops to use phis and 
partial destruction.

Douglas Gregor 3bdcff5866 When instantiating a C++ "new" expression, don't fake source locations 
for the '(' and ')' around the initializer unless we actually have an
initializer. Fixes PR10197, an issue where we were value-initializing
rather than default-initializing.

John McCall 7ec4b4342c Don't actually emit calls to the reserved global placement new and delete 
operators;  their semantics are guaranteed by the language.

If someone wants to argue that freestanding compiles shouldn't recognize
this, I might be convinceable.

Douglas Gregor 040ad500c4 Fix a few more ConvertTypes that should be ConvertTypeForMems, fixing 
two regressions in Boost.Config.

John McCall 8ed55a54fd Abstract IR generation of array cookies into the C++ ABI class and 
implement ARM array cookies.  Also fix a few unfortunate bugs:
  - throwing dtors in deletes prevented the allocation from being deleted
  - adding the cookie to the new[] size was not being considered for
    overflow (and, more seriously, was screwing up the earlier checks)
  - deleting an array via a pointer to array of class type was not
    causing any destructors to be run and was passing the unadjusted
    pointer to the deallocator
  - lots of address-space problems, in case anyone wants to support
    free store in a variant address space :)

Argyrios Kyrtzidis 7648fb464b Fix miscompilation. The cookie was not used when new'ing arrays with multiple dimensions.

Douglas Gregor c1a42fdd53 Make sure to add MallocAttr to explicitly-declared operator new/new[] 
when -fassume-sane-operator-new. Patch by Tom Jablin!

Douglas Gregor 05fc5be32f Implement zero-initialization for array new when there is an 
initializer of (). Make sure to use a simple memset() when we can, or
fall back to generating a loop when a simple memset will not
suffice. Fixes <rdar://problem/8212208>, a regression due to my work
in r107857.

Nuno Lopes 13c88c7269 implement PR5654: add -fassume-sane-operator-new, which is enabled by default, and adds the malloc attribute to the global function new() and to the overloaded new operators.

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).
