This reverts commit a31cef44. Original message: [heap] Divide available memory upon compaction tasks - Fairly (round-robin) divide available memory upon compaction tasks. - Ensure an upper limit (of memory) since dividing is O(n) for n free-space nodes. - Refill from free lists managed by sweeper once a compaction space becomes empty. Assumption for dividing memory: Memory in the free lists is sparse upon starting compaction (which means that only few nodes are available), except for memory reducer GCs, which happen in idle time though (so it's less of a problem).

Set "no recover" in diagnostic mode to keep triggering crashes. Otherwise, the v8 test driver won't notice tests as failing. Also port some common sanitizer cflags to cfi - those can be removed on the build side afterwards.

This makes sure that initializing assignments of let-declared variables perform an environment lookup and hence keep the variable alive. This is needed because full-codegen contains debug code verifying the variable is still inside the TDZ at the initializing assignment.

When eagerly parsing arrow functions, expressions in default parameter initializers are parsed in the enclosing scope, rather than in the function's scope (since that scope does not yet exist). This leads to VariableProxies being added to the wrong scope, and scope chains for FunctionLiterals being incorrect. This patch addresses these problems by adding a subclass of AstExpressionVisitor that moves VariableProxies to the proper scope and fixes up scope chains of FunctionLiterals. This is a revert of the revert https://crrev.com/e41614a058426fb6102e4ab2dd4f98997f00c0fc with a much-improved (though not yet perfect) Scope::ResetOuterScope method which properly fixes not only the outer_scope_ pointer but also fixes the inner_scope_ list in the relevant outer_scopes. More work likely still needs to be done to make this work completely, but it's very close to correct.

port d515e513(r31211). contributed by zhengxing.li@intel.com original commit message: Previously, name conflicts between var and let declarations were only made into exceptions if they were visible at parse-time. This patch adds runtime checks so that sloppy-mode direct eval can't introduce conflicting var declarations. The change is implemented by traversing the scope chain when a direct eval introduces a var declaration to look for conflicting let declarations, up to the function boundary. additional comment: The original r31211 patch needs some additional changes for x87 1. Should use Smi::FromInt(variable->DeclarationPropertyAttributes()) BUG= Review URL: https://codereview.chromium.org/1420683002 Cr-Commit-Position: refs/heads/master@{#31433}

Revert "Revert of [turbofan] Splinter into one range. (patchset #2 id:80001 of https://codereview.chromium.org/1391023007/ )" This reverts commit 23a8837f. Also added a CHECK in Merge to validate that splitting yields a different range and thus advances the algorithm. Ran stress bots successfully. Likely my earlier change in Splintering addressed the stress test scenario that was looping infinitely.

Adds an implementation of "do expression" parsing (https://webcache.googleusercontent.com/search?q=cache:MIGALjqPDNgJ:wiki.ecmascript.org/doku.php%3Fid%3Dstrawman:do_expressions+&cd=1&hl=en&ct=clnk&gl=us). This feature provides a way to evaluate a block of statements within an expression context, producing the resulting completion value. This is very helpful for implementing certain language features via desugaring.

range's internal structure, we take a range at a time and splinter based on the blocks it covers. This is no different in scenarios where a UseInterval covers non-deferred then deferred blocks. However, in scenarios where a deferred block jumps to another one, and there are no other blocks covered by the range in between, this CL will treat the two such blocks together, while the previous one would treat them separately. This matters in cases such as deoptimization blocks preceded (not necessarily consecutively) by a single instruction (jump) Merging block.
