Revert of PPC/s390: [ignition] Add call bytecodes for undefined receiver (patchset #1 id:1 of https://codereview.chromium.org/2809743003/ ) Reason for revert: Need to revert: https://chromium-review.googlesource.com/c/463287/ Original issue's description: > PPC/s390: [ignition] Add call bytecodes for undefined receiver > > Port 751e8935 > > Original Commit Message: > > Adds a collection of call bytecodes which have an implicit undefined > receiver argument, for cases such as global calls where we know that the > receiver has to be undefined. This way we can skip an LdaUndefined, > decrease bytecode register pressure, and set a more accurate > ConvertReceiverMode on the interpreter and TurboFan call. > > As a side effect, the "normal" Call bytecode now becomes a rare case > (only with calls and super property calls), so we get rid of its 0-2 > argument special cases and modify CallProperty[N] to use the > NotNullOrUndefined ConvertReceiverMode. > > R=leszeks@chromium.org, joransiu@ca.ibm.com, jyan@ca.ibm.com, michael_dawson@ca.ibm.com > BUG= > LOG=N > > Review-Url: https://codereview.chromium.org/2809743003 > Cr-Commit-Position: refs/heads/master@{#44539} > Committed: https://chromium.googlesource.com/v8/v8/+/41b228057f89e73fbaae867177d523e60d4e92bc TBR=joransiu@ca.ibm.com,jyan@ca.ibm.com,leszeks@chromium.org,michael_dawson@ca.ibm.com,bjaideep@ca.ibm.com # Skipping CQ checks because original CL landed less than 1 days ago.
