Austin Clements fbcf43c60b cmd/compile,cmd/dist,cmd/go: compute -+ flag from package path
As we did for the asm -compiling-runtime flag, this CL modifies the
compiler to compute the -+ (compiling runtime) flag from the package
path. Unlike for asm, some tests use -+ explicitly to opt in to
runtime restrictions, so we leave the flag, but it's no longer passed
by any build tools.

This lets us eliminate cmd/go's list of "runtime packages" in favor of
the unified objabi.LookupPkgSpecial. It also fixes an inconsistency
with dist, which only passed -+ when compiling "runtime" itself.

One consequence of this is that the compiler now ignores the -N flag
when compiling runtime packages. Previously, cmd/go would strip -N
when passing -+ and the compiler would fatal if it got both -N and -+,
so the overall effect was that the compiler never saw -N when
compiling a runtime package. Now we simply move that logic to disable
-N down into the compiler.
