This adds support for get_local and set_local to the wasm compile
fuzzer. Each function will have between 0 and 32 locals of random type.
For set_local, we generate a value of the respective type and store it
in the local. For get_local, we load any local and convert it to the
wanted type.
Note that with get_local, we now also check that parameters are passed
correctly between functions.
Drive-by: Fix parameters passed to the main function (was [1,2,3] for
the interpreter, but [1,1,1] for compiled code).

Now that we have an API to request code cache, we want to decouple
compilation from serialization. As a first step, we will add CompileEager
option (used when we want to produce full code cache) and
DeferredProduceCodeOption to NoCacheReason. This is so that we can
properly bucket the compilation time and collect statistics about the
cache behaviour. Once, blink and node start using the new API, we can
remove the code to produce code cache from the compilation.

Extend the code-generator tests to cover AssembleMove and AssembleSwap with
Simd128 registers and stack slots, for targets that support them.
For this to work however, we need support for passing Simd128 stack parameters
in TurboFan which this patch implements for Arm and x86. PPC and S390 both do
not support the Simd128 representation and it appears MIPS and MIPS64's
implementation of AssembleMove and AssembleSwap do not support it either.
As per the design of the tests, the set of values to perform moves on are
represented in a FixedArray of Smis (for kTagged) and HeapNumbers (for kFloat32
and kFloat64). They are converted to raw values for the moves to be performed
on, to be then converted back into a FixedArray. For the kSimd128
representation, we represent values as a FixedArray of 4 Smis, each representing
a lane. They are converted to a raw Simd128 vector using the `I32x4ReplaceLane`
and `I32x4ExtractLane` operations.
Finally, these tests need Simd128 variables mixed with the CodeStubAssembler
which is not a use-case officially supported. And as a result, the `RecordWrite`
stub does not guarantee to preserve Simd128 registers. To get around this, we
have to be careful to skip write barriers when dealing with Simd128 parameters
inside the "teardown" function, and we've had to move all allocations to the
"setup" function.
Thanks to this, we are able to catch bugs such as this one

will always allow previewing ArrayBuffer instances as Uint8Array and
Int8Array. ArrayBuffer instances that have even length will allow
Int16Array preview and ArrayBuffers that have length divisible by 4 will
allow Int32Array previews.

If user redefines some getter on node then it is too easy to detect our
nice tools. Let's make it a little harder.

In tests r6_ldpc and r6_lwupc are accidentally removed instructions
which should be actually tested - LDPC and LWUPC.
(See 822be9b238 "Normalize casing of
hexadecimal digits".)
This CL fixes this error in tests.

This CL adds the i32.trunc_s:sat/f32 WASM opcode to the turbofan
compiler and interpreter (more saturating operators will be added in
later CLs).
The operatation has been added under an experimental flag.

This tests some high-level scenarios of the V8 test runner, with
fake executable, test-suite extension and build configs.
The runners are slightly modified to be easier testable. Args
are passed from the tests now and the V8 root folder can be faked
by the tests.
We support coverage if python coverage 4.0 is installed. Otherwise
we run without it.

Use t9 for the call to C functions instead of t8, since t9 must be used
according to MIPS ABI. This saves us one unneccessary move.
