Bill Budge adc52af506 Reland "[Memory] Use OS::Allocate for all OS memory allocations."
This is a reland of 4899bcb66d
This is a reland of b73ee3344a

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.
>
> - Eliminates OS::ReleaseRegion, replacing with calls to OS::Free.
> - Adds bool return value to OS::Free.
> - Cleans up types of flags, protection on Windows and Cygwin.
