We introduce an explicit LoweringResult data structure. Until this change, the lowering result could be recovered from the node. However, lowering monomorphic loads requires wiring different value and effect, so we need a structure that can express such lowering result.

We reset the profiler ticks when the feedback changes. So, we should not update the feedback when the feedback hasn't changed. Added a check in IC::ConfigureVectorState to see if the feedback has changed before we update the feedback.

The Object.keys builtin didn't properly check for empty_slow_elements_dictionary in addition to empty_fixed_array, which made it miss the fast-path if you used it in combination with like Object.freeze or Object.seal.

Merge some stack operations to work on an even number of registers, adding a padding register where necessary. Some lightly-used macro assembler functions are inlined, to make pairing registers easier. Not all merges create an even number of register arguments yet. This is a step towards aligning the stack pointer to 16-bytes.

During JSTypedLowering, when we see a JSAdd where we know that at least one side is already a String, we can try to strength-reduce the other side to a string as well. And once we have that, check whether both sides are now String constants, and if the concatenation won't overflow the string length limit, we can just constant-fold the StringAdd. This improves the Six Speed template_string benchmarks by up to 5x, as we no longer need to perform the String concatenations on every loop iteration.

Linux builds have an include chain from src/perf-jit.cc: sys/mman.h -> bits/mman.h -> bits/mman-linux.h, which defines a MAP_TYPE macro that conflicts with InstanceType::MAP_TYPE in jumbo builds, for some jumbo_file_merge_limit values. Since MAP_TYPE isn't used in perf-jit.cc, it should be safe to #undef the macro immediately after the sys/mman.h #include statement.

This further reduces the amount of test-specific code. It will also help testing the wasm baseline compiler, since it is also being called from the {WasmCompilationUnit}. Also, move the {RuntimeExceptionSupport} flag from the {WasmFunctionCompiler} to the {TestingModuleBuilder}. There is no need to store this per function builder. The {TestingModuleBuilder} then passes it on to the {WasmCompilationUnit}, which finally sets it on the {WasmGraphBuilder}.

BigInt is a new primitive type of arbitrary precision integers, proposed in https://tc39.github.io/proposal-bigint. This CL introduces a corresponding instance type, map, and C++ class to V8 and adds BigInt support to a few operations (see the test file). Much more is to come. Also, the concrete representation of BigInts is not yet fixed, currently a BigInt is simply a wrapped Smi.
