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.

libraries (from William Lynch).

John McCall 1e67040fb7 Convert the end-catch call for finally blocks to a lazy cleanup. This kills off 
the last of the shared-code cleanups.

John McCall c20acd31f7 Convert the ObjC @synchronized cleanups to laziness. This is not actually 
a big deal, except that I want to eliminate the shared-code EH cleanups
in preparation for a significant algorithmic fix.

Dan Gohman a2489d1bb6 Give MDNode printing has access to the current Module in more 
cases. This will be needed when function-local metadata can
appear in places that aren't intrinsic function arguments.

Jakob Stoklund Olesen 0fef9dda8e Change the createSpiller interface to take a MachineFunctionPass argument. 
The spillers can pluck the analyses they need from the pass reference.

Sean Callanan 1d18066411 Added functionality to dematerialize values that were 
used by the JIT compiled expression, including the
result of the expression.

Also added a new class, ASTType, which encapsulates an
opaque Clang type and its associated AST context.

Refactored ClangExpressionDeclMap to use ASTTypes,
significantly reducing the possibility of mixups of
types from different AST contexts.

Greg Clayton 471b31ce62 Remove use of STL collection class use of the "data()" method since it isn't 
part of C++'98. Most of these were "std::vector<T>::data()" and 
"std::string::data()".

Greg Clayton da9220bbef Added support to MachO.h for many defines and structures that are needed 
to Parse mach-o files. All defines have been renamed to not conflict with
#defines in mach header files, all structures were left named the same but
are in the llvm::MachO namespace.

Dan Gohman 43aa8f03c1 Add support for remapping metadata kind IDs when reading in a 
bitcode file, so that two bitcode files where the same metadata kind
name happens to have been assigned a different ID can still be
linked together.

Eliminate the restriction that metadata kind IDs can't be 0.

Change MD_dbg from 1 to 0, because we can now, and because it's
less mysterious that way.

Chris Lattner 14caa59b14 there is now no reason to link in TARGETS_TO_BUILD since we list 
arm explicitly.  X86 and ARM are the only two targets that support
disassembly, so our explicit list is enough.  These other targets
weren't getting pulled in anyway though, since there were no 
references to their symbols.

enabled.  Add direct ARM support.

Chris Lattner f2f3870189 Follow the implementation approach suggested by PR6687, 
which generates more efficient and more obviously conformant
code.  We now test for overflow of the multiply then force
the result to -1 if so.  On X86, this generates nice code
like this:

__Z4testl:                              ## @_Z4testl
## BB#0:                                ## %entry
	subl	$12, %esp
	movl	$4, %eax
	mull	16(%esp)
	testl	%edx, %edx
	movl	$-1, %ecx
	cmovel	%eax, %ecx
	movl	%ecx, (%esp)
	call	__Znam
	addl	$12, %esp
	ret
