compiler: add intrinsics for runtime/internal/sys functions
runtime/internal/sys.Ctz32/64 and Bswap32/64 are currently
implemented with compiler builtin functions. But if they are
called from another package, the compiler does not know and
therefore cannot turn them into compiler intrinsics. This CL
makes the compiler recognize these functions and turn them into
intrinsics directly, as the gc compiler does.
This CL sets up a way for adding intrinsics in the compiler.
More intrinsics will be added in later CLs.
Also move the handling of runtime.getcallerpc/sp to the new way
of generating intrinsics.

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,

(_Multi_array::__untag_result): Add metafunction to check the function
pointer type for a tag type that dictates the kind of visitation.
(_Multi_array<_Ret(*)(_Visitor, _Variants...), __first, __rest...>):
Use decltype(auto) instead of tagged function pointer type.
(__gen_vtable_impl): Remove bool non-type parameter and unused
_Variant_tuple parameter.
(__gen_vtable_impl::__visit_invoke_impl): Remove.
(__gen_vtable_impl::__do_visit_invoke): Remove.
(__gen_vtable_impl::__do_visit_invoke_r): Remove.
(__gen_vtable_impl::__visit_invoke): Use if-constexpr and __invoke_r
for the visit<R> case, rather than dispatching to separate functions.
(_VARIANT_RELATION_FUNCTION_TEMPLATE): Use __raw_idx_visit and make
lambda return void.
(variant::swap): Likewise.
(__do_visit): Replace two non-type template parameters with a single
type parameter, so that the caller must specify the visitor's return
type (or one of the tag types).
(visit): Deduce a return type from the visitor and use the
__deduce_visit_result tag to enforce that all overloads return the
same type.
(visit<R>): Call __do_visit<R> with explicit result type.
(__variant_hash_call_base_impl::operator()): Use __raw_visit and make
lambda return void.
