    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.
