runtime/pprof: Assume function with no name is in runtime.
GCC PR 65797 causes some of the runtime functions to be
compiled with no name in the debug info. This in turn causes
the runtime/pprof test to fail as reported in GCC PR 64683.
There are no good choices when a function has no name in the
debug info, but here we assume that if we see such a function
while reading the runtime functions, we assume that it is also
a runtime function.

compiler, runtime, reflect: Use reflection string for type comparisons.
Change the runtime and reflect libraries to always use only
the type reflection string to determine whether two types are
equal. It previously used the PkgPath and Name values for a
type name, but that required a PkgPath that did not match the
gc compiler.
Change the compiler to use the same PkgPath value as the gc
compiler in all cases.
Change the compiler to put the receiver type in the reflection
string for a type defined inside a method.
