This reverts commit 671809e6.

Reason for revert: Regresses angle_end2end_test:

ProgramInterfaceTestES31.GetProgramInterface/ES3_1_D3D11

Warning: compileToBinary(232):
C:\fakepath(36,21-40): error X4509: UAV registers live in the same name space as outputs, so they must be bound to at least u1, manual bind to slot u0 failed

The new test and this CL landed at nearly the same time. This CL breaks the test but it wasn't run on the CQ.
