compilers: Fix bitcode and other options for objc code

We were setting the base options for the Objective-C compiler
manually, due to which options such as b_bitcode and b_ndebug were not
getting set at all.

The base options here are the same as for C code with the Clang
compiler, so just use the same inherited list.

Also expand the bitcode test to ObjC and ObjC++ so this doesn't happen
again.
