Removed qalloc and xacc_internal_compiler from XACC

Not exporting the header and compiling these files: to be relocated to qcor.

There are a few unit tests which uses these headers. Will either relocate them to qcor or rewrite this (e.g. ControlledGateTester which doesn't really need qubit types, XASMCompilerTester only has one test for qcor, etc.)

Tested by: compiling xacc
