This is another attempt to reduce how often the assertions are

of _M_key_compare is accompanied by a use of _S_key, so the assertions
can be put in there. For _Hashtable there are member functions that are

compiler: make value method of direct interface type takes pointer
Currently, a value method of a direct interface type takes the
value of the receiver, which is pointer shaped, as the first
parameter. When this method is called through interface, we
actually pass the interface data as a pointer. On most platforms
this is ok, as the underlying calling convention is the same,
except that on SPARC32, the calling convention is actually
different.
This CL changes the method function actually takes a pointer.
The function will convert the pointer to the pointer-shaped
receiver type (a no-op conversion from machine code's aspect).
For a direct call, in the caller we convert the receiver to a
pointer (also no-op conversion) before invoking the method. For
an interface call, we pass the pointer as before. This way, it is
consistent that we always pass a pointer.
Hopefully this fixes SPARC32 build and https://gcc.gnu.org/PR90482.
Currently runtime/internal/atomic functions are implemented in C
using C compiler intrinsics. This CL lets the Go frontend
recognize these functions and turn them into intrinsics directly.

More intrinsics will be added in later CLs.

i386: Emulate MMX vec_dupv2si with SSE
Emulate MMX vec_dupv2si with SSE. Add the "Yw" constraint to allow
broadcast from integer register for AVX512BW with TARGET_AVX512VL.
Only SSE register source operand is allowed.
