Fix LLVM related headers to compile standalone (to fix cpluspluscheck).
Previously llvmjit.h #error'ed when USE_LLVM was not defined, to
prevent it from being included from code not having #ifdef USE_LLVM
guards - but that's not actually that useful after, during the
development of JIT support, LLVM related code was moved into a
separately compiled .so. Having that #error means cpluspluscheck
doesn't work when llvm support isn't enabled, which isn't great.
Similarly add USE_LLVM guards to llvmjit_emit.h, and additionally make
sure it compiles standalone.
Per complaint from Tom Lane.
