Benchmarks showed a large number of useless NCI compilation tasks, i.e. code objects were generated and cached but never used. Ideally, we'd only spawn an NCI task when the generated code will be used in the future. To approximate this behavior, we now delay task creation to the *second* time a function is optimized; the thought being that a function that has been optimized twice is likely to be optimized (= become hot) again in the future.

Load splat implementation is almost the same, except for the vector format used for the output register. We encode this information in MiscField (the size of each lane), and with some helper functions we can easily reuse a single opcode for 4 load splats.

For now, V128 values are converted to String16 (since they are not serializable). It is shown as a list of 16 uint8_t (hex). This description can be tweaked as necessary.

This CL fixes two things: 1) It properly creates code entries for the generic js-to-wasm builtin (others are left out because we don't want to include all builtins in profiles). 2) It includes js-to-wasm frames in profiles. The generic js-to-wasm builtin will map to that frame type in the future (see referenced bug). js-to-wasm frames are currently included because they are wrongly mapped to OPTIMIZED frames by the SafeStackTraceIterator.

We currently have a pattern of setting a dereferenced Handle location to update that Handle's value: *handle.location() = new_value.ptr() This is slightly opaque, and definitely not type-safe, so add a new Handle<T>::PatchValue method which does this operation. Ideally we would make Handle::location() return a const pointer to discourage this sort of use, but there's a bunch of places where that location pointer is used and passed around as a Handle surrogate, so those would have to be updated first.

Currently the kWasmInstanceOffset is computed according to the reg a0(kWasmInstanceRegister)'s position in the frame. And according to Builtins::Generate_WasmCompileLazy, it's the 7th gp_regs that are pushed on to stack, so the index should be 6 other than 7. Since the kWasmInstanceRegister will be pushed on to stack after all parameter registers, so we can use it's index, which does not reply on which reg kWasmInstanceRegister is, and what order the parameter registers are pushed on to stack. So the new index is equal to the number of all parameter registers.

The m (multiline) and s (dotall) flags just needed to be marked as allowed; the required logic was already in the regexp parser. A regexp /<x>/ without the y (sticky) flag is equivalent to the sticky regexp /.*?<x>/y. The interpreter now assumes that every regexp is sticky, and the compiler appends a preamble corresponding to /.*?/ before non-sticky regexps. To reuse existing code for compiling this preamble, the logic for each kind of quantifier is now in a separate function and called from VisitQuantifier and for the preamble. The commit also includes some improvements/fixes for character ranges: - Empty character ranges/disjunctions should never match, but before this commit they would *always* match. - The check of the range bounds in CanBeHandledVisitor was unncessary; without the unicode flag this can't be a range that can't be specified in 2-byte codepoints, and once we support unicode we simply support all codepoints. - The capacity of the list containing the complementary intervals of a character range is now calculated more accurately.

We run tests in parallel which can cause multiple tests to write to the shared v8.log file. This obviously breaks the simple assertions in mjsunit/tools/log.js. - Use temporary files for log testing with --logfile='+' - Change the symbol from '&' to '+' for using temporary files for logging with --logfile - Enable skipped log tests again.

Using associative property of addition: (x + A) + B => x + (A + B). Note: A and B need to have the same sign and we need to check that (x + A) isn't used anywhere else. 20% perf improvement of the following function. function f(n) { var c = 0; for (var i = 0; i < n; i++) { c = c + 2 + 3; } return c; } for n = 10_000_000. Before: 7.31s. After: 6.05s.
