Looks like IBM has added validation for these empty fields.

- Wrap the HetMap helper func. for std::any workaround in ifdef.

- Wno-deprecated-copy is not supported by Clang. Cppmicroservices has Werror flag, hence will cause error if it sees an unknown pragma.

- bind2nd is removed in libstdc++, just use the generic bind w/ placeholder.

- libstdc++ doesn't have std::beta in cmath/math.h. Detect this and use boost instead.

- Explicitly specialize complex<dual> multiplication for autodiff. libstdc++ has a check for floating type which fails the dual type.

- Clang doesn't allow lambda capture of structured binding.

Tested by: compiler.

Added ability to construct `bfunc` instruction.

Also, added ability to load measure results to registers as well as condition instructions based on register value.

Hence, If statements in XACC IR are properly converted to IBM QObj now.
