93e26314af [builtins] Introduce proper Float64Exp operator.
Import base::ieee754::exp() from FreeBSD msun and introduce a Float64Exp
TurboFan operator based on that, similar to what we do for Float64Log.
Rewrite Math.exp() as TurboFan builtin and use that operator to also
inline Math.exp() into optimized TurboFan functions.

89d8c57b9c [builtins] Introduce proper Float64Atan and Float64Atan2 operators.
Import base::ieee754::atan() and base::ieee754::atan2() from fdlibm and
introduce Float64Atan and Float64Atan2 TurboFan operators based on those,
similar to what we already did for Float64Log and Float64Log1p. Rewrite
Math.atan() and Math.atan2() as TurboFan builtin and use the operators
to also inline Math.atan() and Math.atan2() into optimized TurboFan functions.

7ceed92ac0 [builtins] Introduce proper Float64Log1p operator.
Import base::ieee754::log1p() from fdlibm and introduce a Float64Log1p
TurboFan operator based on that, similar to what we do for Float64Log.
Rewrite Math.log1p() as TurboFan builtin and use that operator to also
inline Math.log1p() into optimized TurboFan functions.

Also unify the handling of the special IEEE 754 functions somewhat in
the TurboFan backends. At some point we can hopefully express this
completely in the InstructionSelector (once we have an idea what to do
with the ST(0) return issue on IA-32/X87).

Drive-by-fix: Add some more test coverage for the log function.

d0c7775d7c [builtins] Introduce proper base::ieee754::log.
This switches Math.log to use an fdlibm based version of log, imported
as base::ieee754::log, and use that consistently everywhere, i.e. change
the Float64Log TurboFan operators on Intel to use the C++ implementation
as well (same for Crankshaft).

9dc62d2721 [ic] [stubs] Remove InlineCacheState field from the code flags.
There are no ICs left that store their state in this field: vector based
ICs use feedback vector and the rest three (BinaryOpIC, CompareIC and
ToBooleanIC) reconstruct their state from the ExtraICState field.

This CL also removes unused InlineCacheState::DEBUG_STUB which was used
mostly in Code::is_debug_stub(). The latter now checks if the code is one
of the debug builtins instead.

b4889f7d93 [wasm] New implementation of popcnt and ctz.
This patch provides a new implementation of popcnt and ctz in the case
where the platform does not provide these instructions. Instead of
building a TF graph which implements it we now call a C function.

Additionally I turned on additional tests in test-run-wasm-64.cc

89606003af Always include js-getter as separate field in AccessorInfo
Due to cross-compilation from simulator-builds into non-simulator with snapshot it's complicated to conditionally include an extra field. Given that the memory overhead should be minimal, just always include a separate field instead.

1e3257d27f [Interpreter] Enable tracing of bytecode handler dispatches.
When FLAG_trace_ignition_dispatches is enabled, a dispatch counter is
kept for each pair of source-destination bytecode handlers.

Each counter saturates at max uintptr_t value.

Counters are dumped as a JSON-encoded object of objects, such that
each key on the top level object is a source bytecode name, and each key
on the corresponding value is a destination bytecode name, with the
associated counter as value. The output file name can be controlled
with the FLAG_trace_ignition_dispatches_output_file flag.

The JSON file may be written by calling
Interpreter::WriteDispatchCounters(), which is done for d8 in
Shell::OnExit, if FLAG_trace_ignition_dispatches is enabled.
