Merge branch 'bg/opt-receive' into dev
* bg/opt-receive: Test that gen_server:call/2,3 are fast even with a huge message queue erts: Add tests for the receive optimization Update primary bootstrap erts: Implement recv_mark/1 and recv_set/1 for real compiler tests: Cover the error handling code in beam_receive compiler test: Test optimization of receive statements Optimize selective receives in the presence of a large message queue Introduce the new recv_mark/1 and recv_mark/1 instructions Compile tests that communicate with R12 nodes with the r12 option Move p_run/2 to test_lib gen: Inline wait_resp_mon/2 to help the compiler optimize OTP-8623 bg/opt-receive reveive statements that can only read out a newly created reference are now specially optimized so that it will execute in constant time regardless of the number of messages in the receive queue for the process. That optimization will benefit calls to gen_server:call(). (See gen:do_call/4 for an example of a receive statement that will be optimized.)
