e52907f807 [turbolizer] Features and bug-fixes
Fix bugs and add a few small useful features:

* Fix Schedule view to properly parse schedule output and respond to switching
  back to graph views.
* Add shorcuts for showing edges of selected nodes.
  - 'i' shows all inputs
  - 'o' shows all outputs
  - '1'-'9' shows all nodes nth input where 1 <= n <= 9
  - 'c' shows all control inputs
  - 'e' shows all effect inputs
* Holding the control key down when using a edge-showing shortcut toggles edge
  state rather the just showing.
* 'a' selects all nodes in graph view.
* Node selection is preserved between graph views and Schedule views.
* Holding control key down when using regular expression search shows currently
  hidden nodes that match the regex search.
* Pane expansion buttons now respond to clicks in entire button area.
* Default text in regex search box makes searching more discoverable.

552ba59eb2 [compiler] Remove bailout in ast-numbering's VisitYield.
It's sufficient to bailout when seeing that the function literal is a
generator or async function, as those are the only cases in which there can be
yields.

Also: add a comment on --turbo-from-bytecode and Ignition generators.

cdec5e8d26 Remove erroneous DCHECK related to expression classifiers
It seems that I forgot to remove the DCHECK when refactoring this
function, even though the comment had it right.  It also seems that
this is hard to trigger.  The minimal example I found, after fuzzer's
bug, was:

   eval, x[eval]

31ca317af3 [--runtime-call-stats] Fix ACCESSOR handler computation
When running with FLAG_runtime_call_stats, native accessor accesses must
go through the runtime for accurate accounting. Previously the slow_stub()
was used as a handler in order to accomplish this, but it could never be
looked up from the code cache successfully due to mismatched code flags,
which could cause more handler recompilations than in normal operation.
This patch fixes that by emitting a runtime call into the compiled
handler instead of using the slow_stub().

Drive-by cleanup: drop the unused StoreIC_Megamorphic builtin.

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.

8e1ccba3b0 [turbofan] Retiring Greedy Allocator
We were able to achieve our goals for register allocation independent of
the allocation algorithm. Performance data so far is inconclusive re. the
value of the Greedy algorithm, compared to the particular Linear Scan
implementation we're currently using, and the performance measurement
techniques we currently use are too imprecise to help with this matter.

Retiring the algorithm to lower maintenance and evolution cost (e.g. lower
cost of adding aliasing support). Once we improve benchmarking stability,
and establish a suite sensitive enough for codegen improvement studies,
we may revive the algorithm, should the need arise.

8c1ba59aee RelocInfo modes were not propagated when computing
MemoryOperands, on IA32. This needed to be fixed so that we can
compile wasm code before creating instances, since the compiled code
needs to be patched up for memory and globals references.

This surfaces in asm-to-wasm scenarios.

Added testing (rather, enhanced existing tests).
Note patch#1 where we fail on ia32, and patch#2 with the fix.

It is expected that temporarily used strings die while they are

them.  If they are used for times, externalization will happen
when they move to an old heap.

dfb8d3331e Reduce the memory footprint of expression classifiers
This patch attempts to reduce the (stack) memory footprint of
expression classifiers.  Instead of keeping space in each
classifier for all possible error messages that will
(potentially) be reported, if an expression turns out to be
a pattern or a non-pattern, such error messages are placed in
a list shared by the FunctionState and each classifier keeps a
couple of indices in this list.  This requires that classifiers
are used strictly in a stack-based fashion, which is also in line
with my previous patch for revisiting non-pattern rewriting.

In commit b3bfc0bd58, I corrected the source
position of yield-exceptions by not setting the "return position" on returns
that correspond to yields. It turns out that this caused a bug with debug
stepping. The proper fix is to keep the return position on those returns but
additionally attach the yield's source position to the Throw emitted in
VisitYield.

6c3d43766e [wasm] Turn on parallel compilation by default.
This CL sets the default value of the flag wasm_num_compilation_tasks to 10.
The actual number of compilation tasks is the minimum of the flag value and
V8::GetCurrentPlatform()->NumberOfAvailableBackgroundThreads(), which is 8
on my machine.
