Subject: Fix several bugs related to hibernate/3 and HiPE

This commit fixes four related bugs:
- calling hibernate/3 using a dynamic call would fail with badarg
as hibernate/3 as a BIF was not implemented. hibernate/3 is generally
provided as a Beam instruction, and code is translated to use this
instruction when loaded.
- calling hibernate/3 from HiPE would fail with badarg because this
would call the aforementioned BIF which was not implemented.
- calling hibernate/3 with some HiPE-native garbage in the process heap
would randomly crash at the next garbage collect. This bug only
happened in a complex, yet reproduceable scenarios, where native code
calls beam code that calls hibernate/3, and the process has some
garbage when being hibernated and the process generates garbage when
awaken.
- when entering HiPE, the process current_function can be set and be
inaccurate.

The fix is three folded:
- hibernate_3 BIF now actually works instead of throwing a badarg. While
hibernate_3 BIF was (usually) not called from BEAM, it is called from
HiPE. hibernate behaviour is very close to the scheduler and this is why
it is implemented as an instruction in BEAM. The fix consists in doing
the actual hibernation (through the now exported erts_hibernate
function) and setting the process flag to TRAP as well as the process
status to P_WAITING. On BIF epilogue in both BEAM and HiPE, this status
is tested on TRAP and if set, the scheduler is invoked. The i_hibernate
instruction and translation code is now redundant and could be deleted.
- hibernation now also empties the HiPE native stack, with a new
function hipe_empty_nstack provided by Mikael Pettersson.
- when entering HiPE through hipe_mode_switch, p->current is cleared,
as suggested by Mikael Pettersson. p->current normally hold a pointer to
the {M,F,A} of the current function if it exists. When hibernating, it
is set to {erlang,hibernate,3}, and all stdlib hibernate tests
(gen_server_SUITE:hibernate/1, proc_lib_suite:hibernate/1, etc.)
actually rely on this information. Clearing p->current fixes the tests
and avoids the surprise one might have when querying the process info
of a process that hibernated and woke up in a native function.

Non-regression tests are provided, a test for the dynamic call as well
as a Makefile-handled duplication of the hibernate_SUITE into
hibernate_native_SUITE for the HiPE case.

Subject: Remove hipe constants pool

Hipe constants used to be allocated within a single, fixed-size pool for
interaction with the garbage collector. However, the garbage collector
no longer depends on constants being allocated within a single pool, and
the fixed size of the pool both meant unnecessary allocations on most
deployments and crashes on deployments requiring more constants.

The code was simplified to directly invoke erts_alloc.
Debugging and undocumented function hipe_bifs:show_literals/0 was
removed (it returned true and output text to the console), and
debugging and undocumented function hipe_bifs:constants_size/0 was
rewritten with a global to count the size of allocated constants.

Subject: Fix 18 exabyte memory allocation failure

The new_binary() function takes a size argument that is an
int. In the 64-bit emulator (sizeof(int) == 4, sizeof(Uint) == 8),
any sizes >= 0x8000000 become 0xffffffff80000000 and above and
triggers a memory allocation failure.

Change the type of the size argument to Uint, and change any
callers that cast the argument to an int.

Subject: Make halfword emulator with valgrind target allocate low memory

Limit ERTS_MSEG_FAKE_SEGMENTS (that is otherwise set for valgrind
target) to not apply to low memory needed by halfword emulator. This
will reduce the fault detection capability of valgrind for low memory.

Also correct a bug in the initial mmap and make sure the returned
memory region does not reach into high memory.
