The current_cpu value was erroneously removed from the build config json.
In multi-arch builds, each toolchain subdirectory in the build-product
output emits its own build-config json, where current_cpu determines
the architecture type of the sub-build.
Correctness-fuzzer runs could wrongly determined x86 sub-builds as x64.

Now that the maximum string length varies between platforms, the
correctness fuzzer is unhappy. It will ignore crashes, so when we know
we have reached platform-dependant behavior just crash if
--abort_on_stack_overflow is enabled.
Also rename abort_on_stack_overflow to
abort_on_stack_or_string_length_overflow.

1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

Most of these suppressions were for the old asm-validator or for the old compiler pipeline. Some more are just optimistically removed.

This adds a new "ignition_asm" configuration for the correctness fuzzer.
It is intended to compare execution behavior of asm.js modules (either
valid or invalid) that are translated to WASM, against baseline Ignition
execution. There should be no observable difference between these two
configurations.

The previous method was too brittle as applying a variable number of arguments to Date can be manipulated in too many ways, e.g. concat and apply semantics.

This adds optional multi-architecture builds, allowing to compile
x86 and x64 in one build. The correctness fuzzer can be configured to
compare the two executables, e.g. to compare x86 to x64 run the
launcher with: --second-d8=clang_x86/d8 in an x64 build.
Configuring the executable's architecture is now simplified and
inferred from the gn build configuration.
Building for clusterfuzz has now a new canonical target that can be
used by the infrastructure (defaults to d8).
The clusterfuzz release builder is now defined to compile
multi-arch builds, which will have an effect as soon as the
infrastructure refers to the new clusterfuzz target.
