For Divide operations like r = a / b where r has only truncated uses (i.e. only used in bitwise operations), we used to generate a Float64Div unless we statically knew something about a and b, even if a and b have always been integers so far. Crankshaft was able to generate an integer division here, because Fullcodegen collected feedback independently for inputs and outputs of binary operations. This adds new BinaryOperationFeedback::kSignedSmallInputs, which is used specifically for Divide to state that we have seen only SignedSmall inputs thus far, but the outputs weren't always in the SignedSmall range. The issue was discovered in a WebGL Triangulation library and reported via https://twitter.com/mourner/status/895708603117518848 after Node 8.3.0 was released with I+TF.

This changes the baseline of an inspector test setting breakpoints within an asm.js module while the module is being executed. With the validator it is not supported to switch from active WebAssembly code back to debuggable interpreter code. Hence some previously expected breakpoints no longer fire, the behavior is consistent across all configurations now though.

PatternRewriter is an implementation detail of the Parser; as such, there's no need for it to be exposed in parser.h (or even to most of the Parser). This patch is a cleanup that hides all of PatternRewriter in pattern-rewriter.cc, exposing only the few helper methods needed by the rest of Parser in parser.h. Also removed some duplication between the two PatternRewriter initialization functions by adding a constructor, and added a few DCHECKs here and there.

This patch merges ObjectMarking and MarkingState. The new marking state encapsulates object marking, live byte tracking, and access atomicity. The old ObjectMarking calls are now replaced with calls to marking state. For example: ObjectMarking::WhiteToGrey<kAtomicity>(obj, marking_state(obj) becomes marking_state()->WhiteToGrey(obj) This simplifies custom handling of live bytes and allows to chose atomicity of markbit accesses depending on collector's state. This also decouples marking bitmap from the marking code, which will allows in future to use different data-structure for mark-bits.

Mutating the descriptor array and the layout descriptor of a map races with the concurrent marking. This patch simply transfers ownership of the descriptor array without mutating the map. Since the old map is not going to be used anymore and there are not transitions from the old map, this should be safe for trimming the descriptor arrays during GC. This patch also adds checks in IC code avoid caching of dummy transitions from the abandoned prototype map.

The run_test.py tool test selection only expands asterisks at the end of the test name. This CL introduces glob expansion in test selection (asterisks are expanded anywhere in the path). This is useful when tests that belong to the same area have different prefixes. For example wasm cctests have two different prefixes: 'cctest/test-run-wasm*' and 'cctest/test-wasm*'. With this CL it is possible to specify the selector 'cctest/*wasm*' to run them all.
