Add the necessary V8_EXPORT_PRIVATE attributes and a few other minor changes to make building DLLs with MSVC happy. (Note: Debug builds still seem to be failing in Torque, but this fixes Release builds).

Change SlotSet representation to a variable-sized array of pointers to buckets. The length of the array/number of buckets depends on the size of the page. Before this change the SlotSet always stored a fixed number of buckets. Large pages needed a SlotSet-Array to cover the whole object. Now both regular and large pages both use a single SlotSet object, which contains all bucket pointers.

According to the specification, class-specific {operator new} and {operator delete} should be static methods. Interestingly, if the {static} keyword is missing, the methods are implicitly static anyway. This is confusing, so this CL adds the {static} keywords explicitly. It also removes the redundant {Malloced::New} and {Malloced::Delete} methods.

We already use {base::AddressRegion} in some places, while other places still receive {Address} and {size_t}. Those are often created from an existing {base::AddressRegion}, hence pass that on explicitly. Drive-by: Rename {AssignRanges} to {AssignRange}. Drive-by^2: Return {base::AddressRegion} by value (it is trivially copyable and small).

The "Address" type is V8's general-purpose type for manipulating memory addresses. Per the C++ spec, pointer arithmetic and pointer comparisons are undefined behavior except within the same array; since we generally don't operate within a C++ array, our general-purpose type shouldn't be a pointer type.

MSVC 2015 and 2017 implement std::is_trivially_copyable, but not correctly. Hence, reimplement it using more low-level primitives. For stdlibc++ versions below 5.0, we already have a workaround for the missing support of std::is_trivially_copyable, but this is an unsound approximation, because it is ignoring move constructor, move assignment and copy assignment. Therefore, do not use this approximation for asserting trivial copyability of a type. Finally, add unittests for the new is_trivially_copyable implementations.

- 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.

- Moves GetRandomMmapAddr from platform to v8::internal allocation primitives, in preparation for delegating this to the embedder. - Adds hint parameters to OS functions that used to use this function.
