[inspector] removed break location right before suspension in async function In current implementation in expressions like await foo() we have break location right after foo call and before actual await. And we additionally have a lot of other statement locations because of do scope. Let's move async debugging closer to sync debugging and introduce only one break location for await - before awaited function call. Bug: v8:6425,v8:6162 Change-Id: I7568767856022c49101e7f3b7e39a2e401d21644 Reviewed-on: https://chromium-review.googlesource.com/514046 Reviewed-by: Marja Hölttä <marja@chromium.org> Reviewed-by: Dmitry Gozman <dgozman@chromium.org> Commit-Queue: Aleksey Kozyatinskiy <kozyatinskiy@chromium.org> Cr-Commit-Position: refs/heads/master@{#45625}

[async-await] desugar Await in BytecodeGenerator This includes several changes. From most to least interesting: - No longer implement AwaitExpressions using a do-expression. - Reduces frame-size of async generators by not allocating temporary variables to hold results of Await epxressions. - Streamline and reduce generated bytecodes for Await. - Debugger no longer emits a debug::kCallBreakLocation breakpoint for the JS-builtin call performed for Await, and instead only emits such a breakpoint if the operand of Await is actually a call. - Push fewer parameters to Await* builtins, using the receiver for the first parameter (possible now that the CallRuntime invocation not part of the AST). - Adds a new Await AST node. No new members or anything, but it seemed palatable to avoid having `if (is_await())` in a number of VisitSuspend functions.
