86bd2b3c23 Revert of Disable non-standard Promise functions in staging (patchset #5 id:80001 of https://codereview.chromium.org/1469543003/ )
Reason for revert:
[Sheriff] This breaks ignition on arm sim debug:
https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20arm%20-%20sim%20-%20debug/builds/5317

Seems to not be caught by the cq bot that builds release with dchecks.

a1ba971cd8 [Interpreter] Enable assignments in expressions.
This change introduces register re-mapping to avoid assignment hazards
in binary expressions. Expressions that cause problems typically have
the form y = x + (x = 4);. The problem occurs because the lhs value
evaluates to the register holding x. The rhs updates that register and
then applying the operation would use the new value as the lhs.

By tracking loads and stores in binary expressions the generator is now
able to detect when condition occurs and uses a temporary register for
the rhs value. When the binary expression evaluation is complete the
variable is updated with the latest temporary.

A new bytecode Mov performs this update without touching the
accumulator.

f6e689cebb [turbofan] Implemented the TruncateFloat64ToUint64 TurboFan operator.
The TruncateFloat64ToUint64 operator converts a float64 to an uint64 using
round-to-zero rounding mode (truncate). If the input value is outside uint64
range, then the result depends on the architecture. I provide an implementation for x64 and arm64.

@v8-ppc-ports and @v8-mips-ports, can you do the implementations for ppc64 and mips64?

This adds an explicit parameter to the call descriptor having kind
kJSCallFunction representing the new.target value. Note that for now
this parameter is not yet passed in and hence cannot be used yet. Also
contains some refactoring of how parameter index value are calculated,
establishing Linkage as the central point for such index computations.

This is a preparatory CL to allows us passing new.target in a register
instead of via a side-channel through the construct stub frame.

0514fa204a [heap] make inline-allocation-observers precise
Now that we no longer require AllocationInfo::limit to be aligned [1], we can do
more accurate inline-allocation-observation. This lets us get notified when the
next allocation that crosses the step-size boundary is allocated.

Fixed the test-cases. They make significantly more sense now given the step
sizes and the number of times we get notifications. For example, with a step
size of 512, an allocation of 16kb results in 32 notifications instead of 30
now.
