These copies would coalesce easily, but the resulting value would be
defined by a deleted instruction. Now we also remove the undefined value
number from the destination register.

This fixes PR10503.

I'm not completely sure the standard allows us to reject this, but if it doesn't, it should. :)

On x86 we can't encode an immediate LHS of a sub directly. If the RHS comes from a XOR with a constant we can
fold the negation into the xor and add one to the immediate of the sub. Then we can turn the sub into an add,
which can be commuted and encoded efficiently.

This code is generated for __builtin_clz and friends.

1. Attempting to delete an expression of incomplete class type should be an error, not a warning.

2. If someone tries to delete a pointer to an incomplete class type, make sure we actually emit
the delete expression after we warn.

different from the previous 128-bit because they work in lanes.
Update a few comments and add testcases

@interface Foo : NSObject
@property (readonly) id myProp;
@end

@implementation Foo
@synthesize myProp;
@end

t.m:9:13: error: ARC forbids synthesizing a property of an Objective-C object with unspecified storage attribute
@synthesize myProp;
            ^

which is fine, we want the ownership of the synthesized ivar to be explicit. But we should _not_ emit an error
for the following cases, because we can get the ownership either from the declared ivar or from the property type:

@interface Foo : NSObject {
	__weak id _myProp1;
	id myProp2;
}
@property (readonly) id myProp1;
@property (readonly) id myProp2;
@property (readonly) __strong id myProp3;
@end

@implementation Foo
@synthesize myProp1 = _myProp1;
@synthesize myProp2;
@synthesize myProp3;
@end

Allow the rot_imm operand to be optional. This sets the stage for refactoring
away the "rr" versions from the multiclasses and replacing them with Pat<>s.

Start of cleaning this up a bit. First step is to remove the encoder hook by
storing the operand as the bits it'll actually encode to so it can just be
directly used. Map it to the assembly source values 8/16/24 when we print it.

Report more memory using in Preprocessor::getTotalMemory() and PreprocessingRecord::getTotalMemory().

Most of the memory was already reported; but now we report more memory from side data structures.

end of list test function as __eol_test__.

The simple example can be reduced to:

    for t in task_head.linked_list_iter('next'):
        print t

Modify the test program to exercise the API for both cases: supplying or not
supplying an end of list test function.
