    Description

      After JDK-8150921, most Unsafe{Get,Put}Raw intrinsic methods can be replaced by Unsafe{Get,Put}Object.

      There is the only occurrence where c1 refers UnsafeGetRaw among GraphBuilder::setup_osr_entry_block(). We can replace UnsafeGetRaw with UnsafeGetObject when setting up OSR entry block. After that, Unsafe{Get,Put}Raw can be completely removed.
