It has been changed so that now they use different addressing modes
and thus different MC representation (Operand Infos).  Modify the
disassembler to reflect the change, and add relevant tests.

Fix a problem where we were looking up the class pointer in the {class/sel -> implementation} cache for a objc_msgSendSuper call - where we should have looked up the class's super-class.

BuildUDIV: If the divisor is even we can simplify the fixup of the multiplied value by introducing an early shift.

This allows us to compile "unsigned foo(unsigned x) { return x/28; }" into
	shrl	$2, %edi
	imulq	$613566757, %rdi, %rax
	shrq	$32, %rax
	ret

instead of
	movl    %edi, %eax
	imulq   $613566757, %rax, %rcx
	shrq    $32, %rcx
	subl    %ecx, %eax
	shrl    %eax
	addl    %ecx, %eax
	shrl    $4, %eax

Add an argument to APInt's magic udiv calculation to specify the number of bits that are known zero in the divided number.

This will come in handy soon.

I have convinced myself that it can only happen when a phi value dies. When it
happens, allocate new virtual registers for the components.

Fix PR9488: 'auto' type substitution can fail (for instance, if it creates a reference-to-void type). Don't crash if it does.
Also fix an issue where type source information for the resulting type was being lost.

Don't construct two CFGs just to run -Wuninitialized.  While this causes new warnings to be flagged under -Wconditional-uninitialized, this is something we

Tweak RegionStore's handling of lazy compound values to use the 'Default' versus 'Direct' binding key, thus allowing specific elements of an array/struct to be overwritten without

read the memory contents of the function, and then feed the bytes to the

It uses the pexpect module located under ToT/test/pexpect-2.4 directory to
