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.

Chris Lattner 75217e8cb7 fix edis to only try to link in the x86 parts if the x86 backend is 
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

Chris Lattner 26008e07de implement rdar://5739832 - operator new should check for overflow in multiply, 
causing clang to compile this code into something that correctly throws a
length error, fixing a potential integer overflow security attack:

void *test(long N) {
  return new int[N];
}

int main() {
  test(1L << 62);
}

We do this even when exceptions are disabled, because it is better for the
code to abort than for the attack to succeed.

This is heavily based on a patch that Fariborz wrote.

Douglas Gregor af82e3510b Introduce a new lexer function to compute the "preamble" of a file, 
which is the part of the file that contains all of the initial
comments, includes, and preprocessor directives that occur before any
of the actual code. Added a new -print-preamble cc1 action that is
only used for testing.
