If an intrinsic is called through MethodHandle and it contains a call, 
then it crashes at the call site during resolution due to inconsistent 
symbolic info: bytecode refers to method handle linker (MH::linkTo*), 
but the call invokes some concrete method (result of inlining through 
the linker).

The fix is to explicitly attach symbolic info to the call using the 
machinery introduced by JDK-8072008 [1].

Testing: hs-precheckin-comp, hs-tier1, hs-tier2, hs-tier3
