Darwin is able to use two runtimes for objective-c; the
default is its native "NeXT" runtime, but also it can build
code using the "gnu-runtime". In order to do this, we have to
be able to find the gnu-runtime headers (which are installed
into the compiler's tree).
The process to do this is erroneously prepending the sysroot

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.

Replace _Equal_helper with simpler class template
By defining the new helper inside _Hashtable_base it doesn't need all
the template parameters to be provided, and by making it only
responsible for checking a possibly-cached hash code it only has to do
one thing. The caller can use the equality predicate itself instead of
duplicating that in the helper template.

compiler: improve escape analysis on interface conversions
If an interface does not escape, it doesn't need a heap
allocation to hold the data (for non-direct interface type).
This CL improves the escape analysis to track interface
conversions, and reduces these allocations.
Implicit interface conversions were mostly added late in the
compilation pipeline, after the escape analysis. For the escape
analysis to see them, we move the introduction of these
conversions earlier, right before the escape analysis.
Now that the compiler can generate interface conversions inlined,
gcc/testsuite/go.test/test/nilptr2.go needs to be adjusted as in
golang.org/cl/176579, so the use function does an actual use.
