For handling restartability issues, following conditions must be fulfilled: - For Branch-and-link restartability: GPR 31 (ra register) must not be used for the source register rs. - For Jump-and-Link restartability: Register specifiers rs and rd must not be equal. This CL implements checking that GPR 31 is not used as source register.

Adds a CheckString to all operand inputs of JSStringConcat. The operands are already known to be strings, so this will get eliminated in almost all cases, however, if there is a yield within the concatenation then we lose the knowledge that the previous operands are strings since the values are loaded from the generator object. Adds a test for this case.

The Construct bytecode is always passed a valid feedback slot (just like the Call bytecode), so no need to check for invalid feedback slot anymore. Also perform the call count increment initially for both bytecodes instead of delaying it, which decreases live range for the feedback vector and slot registers.

Uninitialized property accesses are replaced with SOFT deopts in TurboFan, but uninitialized JSCall nodes are not, and instead they just stick around and are also not being inlined because the heurstic in TurboFan doesn't consider those candidates since their call frequency is below the threshold. This unifies the behavior and also replaces uninitialized calls with SOFT deopts, addressing some inconsistency in optimization behavior as discovered by Brian White of Node for example here: https://twitter.com/mscdexdotexe/status/879005026202640385 R=jarin@chromium.org BUG=v8:4551, v8:5267 Review-Url: https://codereview.chromium.org/2956843002 Cr-Commit-Position: refs/heads/master@{#46231}

This is towards closing the perf gap between the MSVC build (which uses link- time optimization) and Clang (where LTO isn't ready on Windows yet). We did a study (see bug) to see which non-inlined functions are hit a lot during render start-up, and which would be inlined during LTO. This should benefit performance in all builds which currently don't use LTO (Android, Linux, Mac) as well as the Win/Clang build. The binary size of chrome_child.dll increases by 2KB with this.

This removes support for code-stub to tail-call into the runtime via the deoptimizer. The Hydrogen code-stubs would trigger a deopt in order to materialize a trampoline frame, which would then continue execution in a runtime function associated with each stub. This is no longer needed for code-stubs built with the CSA.
