This adds an arena allocator that can be used as a drop-in replacement for
NSPR's PLArena. Example usage for defining an 8-byte aligned allocator that
uses a 4K arena size:
mozilla::ArenaAllocator<4096,8> a;
void* memory = a.Allocate(200);
There's an antipattern where nsLiteralString is used as an unnecessary intermediary in converting from CharT* to CharT*,
e.g. CallAFunctionThatTakesACharPointer(NS_LITERAL_CSTRING("foo").get());
or
NS_NAMED_LITERAL_STRING(foo, "abc");
CallAFunctionThatTakesACharPointer(foo.get());
This patch rewrites the callsites that can be trivially changed to use char*/char16_t*.
I'd somewhat like to remove nsTLiteralString::get() altogether, but in code that's less straightforward than these examples, get() is useful enough to keep.

This just-so-happened to work because nobody refers to the splitter directly by name.
The added gtest doesn't actually prove that this patch fixes anything, but I figured we could use a wide string for good measure.

Handling potential nsDeque size changes means a bit of extra work.
But if the nsDeque is const, we can assume that it shouldn't get modified, so
we can provide a more optimized iterator that doesn't need to handle size
changes.
Optimizing a range-for loop in which the deque is not modified, can be done
by writing: `for (void* item : const_cast<const nsDeque&>(deque)) {...}`

Note that iterators stay at the same index if the deque size changes
(including end-iterators staying at the end).
This means that after front operations, iterators will effectively point at
different elements! (Possibly skipping or re-visiting some.)
But this is consistent with ForEach and hand-crafted index-based for loops.

It's now possible to write:
for (void* item : deque) { ... }

There are several XPCOM tests that purport to call
NS_RegisterStaticAtoms. The tests located in the xpcom/tests/ directory
are unused, so we might as well just remove them. The gtests do get
run, but there's going to be no way to test NS_RegisterStaticAtoms once
sealing the atom table actually means forbidding new additions. So we
might as well remove the gtest too.
This change is mostly straightforward, except for the following.
- It removes all the printing from the do_check_* macros because gtest macros
do appropriate printing.
- test_StatementCache.cpp needs some special gtest magic for the type
parameterization.
- It merges the four tests in test_unlock_notify.cpp because they rely on being
executed in order, and so aren't independent.
- storage_test_harness_tail.h is no longer necessary because gtest provides the
test looping functionality.
- It uses #include and the preprocessor to remove the duplication between
test_deadlock_detector.cpp and xpcom/tests/DeadlockDetector.cpp.
- It makes the test in test_service_init_background_thread.cpp a death test to
force it to be the first storage gtest, because it fails otherwise.
- It adds code to undo the SQLite mutex hooking as necessary, so that tests
don't interfere with each other.
- It de-virtualizes Spinner's destructor (as identified in bug 1318282).
