port fbad6366 (r30467) original commit message: The call protocol requires that the register dedicated to the number of actual arguments (i.e. rax on x64) always contains the actual arguments. That means after adapting arguments it should match the number of expected arguments. But currently we pass some semi-random value (usually some stack address) after adapting arguments. It looks like this is currently not observable anywhere, because our builtins and functions either don't look at the number of arguments and just make hard coded (unchecked) assumptions, or are marked as "don't adapt arguments", which bypasses the broken code in the trampoline for arguments adaption. Nevertheless this should be fixed. BUG= Review URL: https://codereview.chromium.org/1304893010 Cr-Commit-Position: refs/heads/master@{#30605}
