166863b6b4 MIPS[64]: Optimize the size of deoptimizer table on MIPS R6
On MIPS R6 we have BC instruction that has 26bit offset. We exploit this
in order to generate deoptimizer table with two instructions per entry
instead of earlier three instructions per entry.

6c85ae7039 [arm] Cleanup MacroAssembler::PrepareCallCFunction to use ip
The PrepareCallCFunction methods would take a scratch register as arguments when
they can simply use ip. The reason to do this, apart from simplifying the code,
is that TurboFan's code generator uses r9 as a scratch for this when it could
just as well use ip.

b9b8cc9bad Expose %ErrorPrototype% as an intrinsic in the public API.
Blink needs %ErrorPrototype% in order to properly set up the inheritance
chain from DOMException, as specified in WebIDL:
https://heycam.github.io/webidl/#es-DOMException-specialness

This patch is similar to commit 5ec1cddcd ("Expose %IteratorPrototype% as an
intrinsic in the public API"), with the difference that there was no entry
for %ErrorPrototype% in any of the mappings in contexts.h.

f4d9561ad2 PPC/s390: Don't dereference handles in (macro-)assembler functions used by TF.
Port 9b3174b295

Original Commit Message:

    Remove all IsHeapObject/IsSmi checks from assembler and also from
    the macro-assembler functions that Turbofan code generation uses.

    Note for porters: In case it's unclear which macro-assembler
    functions need to be modified, it may be best to wait until I
    split MacroAssembler in a followup-CL, which will make that clear.

aeb8f33204 [api] remove --harmony-function-tostring behavior from CompileFunctionInContext
The ')'-in-parameter checking is not necessary for
CompileFunctionInContext. The arguments array is expected to be an
array of identifiers, not an array of arbitrary strings that get
concatenated.

Furthermore, there's no reason to have the .toString() representation
look like it came from CreateDynamicFunction(), and in fact inserting
line breaks makes it more complicated to map line and column numbers
correctly.

Overall, the --harmony-function-tostring behavior only makes
CompileFunctionInContext worse, so this CL removes it.

28cc5dc672 Reland [wasm] Allow the initialization of a single compilation unit
Tsan figured out that I called compilation_units_.empty() outside a
lock.

Original message:
This CL adds a new function {InitializeCompilationUnit} to initialize
a single compilation unit and not just all compilation units at once.
This is necessary for streaming compilation eventually. This also
required some refactoring on how the working queue for compilation units
works. Previously the synchronization was done with an atomic counter,
now it is done with a lock. Note that the code to finish compilation
of a module still only works if the working queue gets only empty when
all work is done. I plan to change this in a different CL.

Since the code would not be tested without streaming compilation, I added
an experimental flag and a test to test the new code.

641705e0c0 Reland [wasm] Check the size of a function body before storing it
In the original CL I moved an error check backwards, unfortunately
behind a vector lookup which should not happen when there is an error.
Now I also move the vector lookup backwards.

Original message:
We stored the size of a function body before we check that
these values are valid. This caused a failing DCHECK in the constructor
of WireBytesRef which checked for integer overflows. With this CL we
check the size of the function body before we create the WireBytesRef.

b9ee0657c6 [builtins] Unified C++ implementation of Map and Set iterators.
This is the first step in optimizing Map and Set iterators. This ports
all the base functionality including

 - Set.prototype.entries
 - Set.prototype.values
 - %SetPrototypeIterator%.next
 - Map.prototype.entries
 - Map.prototype.keys
 - Map.prototype.values
 - %MapPrototypeIterator%.next

to C++ and removes all the dead code and the previous half JavaScript
implementation. The next step is to port core parts to CodeStubAssembler
and finally inline the fast-paths into TurboFan directly. The relevant
design document is at:

  https://docs.google.com/document/d/13z1fvRVpe_oEroplXEEX0a3WK94fhXorHjcOMsDmR-8

Most of this work is very similar to how the Array iterator works and we
mostly follow the same process for the implementation.

9b3174b295 Don't dereference handles in (macro-)assembler functions used by TF.
Remove all IsHeapObject/IsSmi checks from assembler and also from
the macro-assembler functions that Turbofan code generation uses.

Note for porters: In case it's unclear which macro-assembler
functions need to be modified, it may be best to wait until I
split MacroAssembler in a followup-CL, which will make that clear.

8e84b715b2 [arm] Introduce UseScratchRegisterScope
Introduce a stripped down version of UseScratchRegisterScope for ARM and use it
inside the assembler and macro-assembler. At the exception of the Call
instructions, we now use this scope instead of using the ip register
directly. This is inspired from how the ARM64 backend works.

In general, the benefit of doing this is we can catch cases where ip is being
used both by the caller and by the assembler. But more specifically, TurboFan
reserves r9 as an extra scratch register because ip can already be used by the
assembler. With this utility, we can isolate the cases in the code generator
which need an extra register and potentially fix them, allowing us to give r9
back to the register allocator.

This patch uncovered places in the assembler where we were using ip
unconditionally when we could have re-used the destination register instead.

00f4b33a65 [arm][turbofan] Pass double immediate to vmov as uint64_t
On x86, signalling NaNs get converted to quiet NaNs when they get push
on the stack and popped again. This happens in the code generation for
arm, specifically for the vmov instruction with the immediate parameter.
This CL replaces the vmov function in assembler-arm to take the
immediate as a uint64_t instead of a double, to guarantee that the bit
pattern does not change even if the parameter is a signalling NaN.
