At the moment, WebAssembly.instantiate(bytes) is implemented by
desugaring it to WebAssembly.compile(bytes).then(WebAssembly.instantiate).
The problem is that the {then} in this snippet is observable. With this
CL I introduce a CompilationResultResolver which allows to do the
desugaring internally and thereby make the {then} unobservable.
Unfortunately the result of WebAssembly.instantiate(bytes) is different
than the result of WebAssembly.instantiate(module). Therefore I also
introduced an InstantiationResultResolver for symmetry with
WebAssembly.compile.

This includes the following changes:
- Limit code space to 128 MB.
- Use direct branches wherever possible.
- Where not possible, continue using load literal followed by an indirect
branch.
- Sort RelocInfo by target_address_address for the serializer, since mixing
load literal instructions and branch instructions messes up that order.
- Ensure we always wipe out targets in the serializer (not just for the
snapshot) in order to be able to distinguish between constant pool entries
and branch instructions.

Linkage-related methods were declared in wasm-compiler.h and
implemented in wasm-linkage.cc. This required all users of e.g. wasm
call descriptors to include the whole wasm compiler header. Also, some
wasm linkage information is independent of turbofan and also used
outside of the compiler directory.
This CL splits off wasm-linkage.h (with minimal includes) and puts it
in src/wasm. This allows to use that information without including
compiler headers (will clean up several uses in follow-up CLs).

Wasm tier-up first compiles the whole module using Liftoff, and then
using Turbofan. The idea is to achieve fast start-up times by first
running Liftoff-compiled code. In the meantime we finish compilation
with Turbofan, and replace the Liftoff-compiled code as soon
as Turbofan finished compilation, thus achieving high performance.
Tier-up is enabled through the flag FLAG_wasm_tier_up.

In order to clarify the difference between, e.g., InstructionStart and
instruction_start, rename as follows:
Code::instruction_start -> raw_instruction_start
Code::instruction_end -> raw_instruction_end
Code::instruction_size -> raw_instruction_size
The difference between the camel-case and raw_* function families is
in how they handle off-heap-trampoline Code objects. For example, when
called on an off-heap-trampoline: raw_instruction_start returns the
trampoline's entry point, while InstructionStart returns the off-heap
code's entry point (located in the .text section of the binary).
Some callsites were updated to call the camel-case function family as
appropriate.

With the Ignition + Turbofan pipeline there is very little overlap between the data
needed for unoptimized compilation and optimized compilation. As a result, it is
cleaner to split up the CompilationInfo into UnoptimizedCompilationInfo and
OptimizedCompilationInfo.
Doing so also necessitate splitting up CompilationJob into UnoptimizedCompilationJob
and OptimizedCompilationJob - again there is not much overlap so this seems cleaner.

The multi-return tests and fuzzer used a custom call descriptor which
was based on the default RegisterConfiguration. This meant that for the
tests, all available registers could be used to pass parameters and to
return values. This caused a problem, because in some cases we need a
scratch register in the frame deconstruction.
With this CL I change both the tests and the fuzzer to use the
WebAssembly call descriptor. Thereby we only use 2 registers for
returns, and one of the other registers can be used as scratch
register.
WebAssembly is the only use case at the moment which wants to return
values not only through registers but also over the stack. Therefore
I think it's acceptable to only test the WebAssembly usecase.

let result;

Note that the first line does not contain a regexp literal, it starts

On arm64, the stack pointer has to be aligned all the time. This
alignment was not considered in the creation of the CallDescriptor in
the fuzzer and thereby caused a mismatch between the CallDescriptor and
code generator. In other words, a callee put return values in a stack
slot which was different than the stack slot where the caller expected
the return value.
With this CL we consider this alignment in the fuzzer.

This CL makes a fuzzer out of the cctest
test-multiple-return/ReturnMultipleRandom. The fuzzer creates a
CallDescriptor with input parameters and returns, and a function which
maps input parameters to returns. The fuzzer then calls this function
with a wrapper which checks that the correct mapping happened.
