match.pd transforms (A&C)|(B&~C) to ((A^B)&C)^B, which is fewer
operations if C is not const (and it is not on simple tests at least,
this transform is done very early already).

Various processors have "insert" instructions that can do this, but
combine cannot build those from the xor-and-xor, especially it has no
chance at all to do that if A or B or multiple instructions as well
(on PowerPC, the rl[wd]imi instructions can do this with together with
a rotate, or a simple shift with appropriate C; other ISAs have similar
insns).

This patch makes RTL simplify transform (xor (and (xor A B) C) B) back
to (ior (and A C) (and B ~C)) for constant C (and similar with A instead
of B for that last term).


	* simplify-rtx.c (simplify_binary_operation_1): Simplify
	(xor (and (xor A B) C) B) to (ior (and A C) (and B ~C)) and
	(xor (and (xor A B) C) A) to (ior (and A ~C) (and B C)) if C
	is a const_int.

    Rename is_immutable to is_static_initializer to try to capture what it
    really means.  Be more precise about when an address expression, or a
    binary expression, can be a static initializer.  Don't check whether a
    type has pointers when deciding whether an initializer must be
    read-write, just check whether it is being used to initialize a global
    variable.  To make that work set the Translate_context function to NULL
    for a global variable with a static initializer.
    
    The effect of this is to let more global variables be initialized
    directly, rather than being initialized in the generated init function.
