	* hooks.h (hook_uint_uintp_false): Declare.

From-SVN: r240389

This patch fixes cost computation in avr_address_cost - instead of the
hardcoded 61, it uses the already existing MAX_LD_OFFSET(mode) macro.

This showed up when investigating a code size regression in the ivopts
pass. That pass computes address_cost with and without an offset to
decide on the right induction variable candidate(s). The legitimate
address target hook returns false for offsets more than 63, so the
pass calls the TARGET_ADDRESS_COST hook with 62 as the offset.

The avr_address_cost hook returns 18 as the cost, and the ivopts pass 
concludes that the cost of address with *any* offset is 18, which is not 
true - the higher cost is incurred only with offsets bigger than MAX_LD_OFFSET. 
This in turn results in a suboptimal choice of induction variables in the
ivopts pass. The patch changes the hardcoded 61 to use the mode
specific MAX_LD_OFFSET instead.

Regression testing with just that fix showed one additional
compilation timeout. That turned out to be the same as
https://lists.nongnu.org/archive/html/avr-gcc-list/2014-03/msg00010.html
- the middle end takes too much time to decide on the best strategy to
multiply DImode values on a 64 bit host. This already causes timeouts
for a few builtin-arith-overflow-* tests (see
https://gcc.gnu.org/ml/gcc-testresults/2016-09/msg02018.html), so it
isn't really related to this fix. Just providing a cost estimate for
DImode mul fixes the timeout though, so the patch does that by scaling
SImode costs by 2 for DImode muls.

With both changes in, there are no regressions, and the
builtin-arith-overflow-* tests now PASS and don't timeout.

    The runtime functions runtime.getcallerpc and runtime.getcallersp are
    intended to be efficient ways to get the return and frame address of the
    caller (that is, the caller of runtime.getcallerpc).  In the C code that
    is implemented by simply using C macros:
    
    This patch essentially implements those macros in the Go code.
    
    It would be nice if we could just use //extern for this, but it doesn't
    work because the runtime code passes the right argument.  Of course we
    could change the runtime code, but these are common enough that I'd
    prefer to avoid the difference from the gc version of the runtime code.
    
    This patch corrects the existing declaration of __builtin_return_address
    to use uint32, rather than uint, for the parameter type.  The builtin
    functions take the C type "unsigned int", which for the targets we use
    corresponds to the Go type uint32.  Not that it should matter, really.
