This patch refactors the runtime support for GET_ENVIRONMENT_VARIABLE to have a single entry point instead of 2. It also updates lowering accordingly. This makes it easier to handle dynamically optional arguments. See also https://reviews.llvm.org/D118777 Reviewed By: jeanPerier Differential Revision: https://reviews.llvm.org/D142489
