Quil visitor to use theta string rather than trying to cast to double

This is problematic when there is a U3 gate: it will create a Ry with string param, then revisit.

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
