review(XXS): 7141059: 7116795 broke pure c2 builds

[Igor Veresov]

7116795 broke pure c2 builds (on x86 and sparc) because it switches TieredCompilation on by default and this, in turn, will the CompilationPolicyChoice to 3, which would fail if TIERED is not defined.

Also, methodHandles.hpp had to be included in frame_{x86,sparc}.cpp in order to building without C1 present.

Thanks!
