      Revert "[Memory] Use OS::Allocate for all OS memory allocations." · 1ea3fd2e
      Bill Budge authored 
      This reverts commit 7e78506f.

Reason for revert: Broke Android build on Arm64.

Original change's description:
> [Memory] Use OS::Allocate for all OS memory allocations.
> 
> - Eliminates OS::ReserveRegion and OS::ReserveAlignedRegion.
> - Changes OS::Allocate to take alignment parameter, reorders parameters
>   to match page_allocator.
> - Since the size of memory allocation can be deduced, don't return the
>   amount of memory allocated.
> - Changes reservation of aligned address space. Before we would reserve
>   (size + alignment) rounded up to page size. This is too much, because
>   maximum misalignment is (alignment - page_size).
> - On Windows and Cygwin, we release an oversize allocation and
>   immediately retry at the aligned address in the allocation. If we
>   lose the address due to a race, we just retry.
> - Clean up all the calls to OS::Allocate in codegen and tests by adding
>   helper AllocateSystemPage function (allocation.h) and
>   AllocateAssemblerBuffer (cctest.h).
> - Changes 'assm' to 'masm' in some targets for consistency when using
>   a macro-assembler.

      [wasm fuzzer] Require AST fuzzer modules to validate · ea08828b
      Eric Holk authored 
      The Wasm AST-based fuzzer is supposed to create valid modules by
construction. This change adds a CHECK to enforce this property.

Additionally, this change exposed several cases where we were not generating
valid modules before:
  * Block types did not match up correctly
  * Memory operations could have invalid alignments
  * Storing an i64 could generate an i32 argument incorrectly.
This CL includes fixes for these issues as well.

      [class] Use CreateDataProperty runtime call · 24b26a0c
      Sathya Gunasekaran authored 
      StoreDataPropertyInLiteral doesn't throw (because the previous uses of
this didn't throw), but class fields can throw on defining the
property which means we can't use this. Changing to CreateDataProperty
runtime call instead.

      We need to throw before rethrowing, otherwise the exception does
not trigger a debugger event and is not reported if uncaught.

      [cpu-profiler] Add static CollectSample method to the CpuProfiler API. · 295c9cc6
      Alexei Filippov authored 
      The method forces all running profilers attached to the provided isolate
to collect a sample with the current stack.

It is going to be used to synchronize trace events generated by embedder with the samples
collected by the profiler.

Also it will finally allow us to break dependency of isolate on CPU profiler.
