Pop call frame before boxing result

After reflective method calls, primitive results need to be boxed
up in an appropriate object.  This generally requires allocating an
object of the appropriate type.  We were doing this before popping
the call frame, which meant that if the allocation caused a GC we
would be scanning results out of a "dead" stack frame.

We hit a case where a register went from holding a reference to
holding a primitive right before the method returned.  The exported
PC was pointing at the last GC point, where the register was expected
to hold a reference, so precise GC was getting very confused.

Bug 3102352.

Use the break position of the current mspace for sizing the zygote heap.

Previously, the mspace footprint used the "overhead" of a heap which
underestimates the size of the zygote heap by 16 bytes, the specific
size of a descriptor deposited at the start of an mspace containing
the control information about that mspace.  If a heap is a multiple of
a page or within 15 bytes of it, the size of the new heap would be
underestimated.

Bad things happened when this underestimate was used to create an
application heap.  The starting address of the application heap was
based on a correctly computed value instead of the underestimate.
This caused the application heap to be one page to large and end one
page beyond where it should.  This additional page happened to overlap
the first page one of the heap bitmaps.  Furthermore, the mspace
routine would proceed access protect that page thinking it was unused
free space.  During the next GC reads to the first page of the bitmap
would generate a SIGSEGV.

By using the break position, correctly rounded, for all sizing
computations this problem no longer exists.

Update the card table scanning for header-only card marks.

Previously, the card table accessors assumed that objects had either
their header marked or would be marked exactly.  As such, after
reckoning a marked card the scan would back up until it found an
object header and then move forward blackening each object within the
address range of the marked card.

Following a recent change we exclusively mark headers.  The scan only
has to move forward until the end of a card.  This saves scanning time
as dlmalloc's binning may leave large segments of the heap unused.  It
is not uncommon for hundreds of cards to be spanned when backing up to
the first live object below a marked card.

In addition, this change fixes the card table verifier to search the
mark stack for gray objects.  It is permissible for roots to point to
white objects on unmarked cards.  This was incorrectly treated as an
error.

Add --uniprocessor option to dex-preopt.

This tells the preoptimizer to target a uniprocessor (unsurprisingly).
By default, it targets SMP, which makes it do more changes than it has
to for a uniprocessor (e.g. editing how non-wide volatile fields are
accessed within bytecode). To be clear, when SMP-optimized code is run
on a uniprocessor, it should still work. We're just aiming to only
make truly necessary changes during optimization.

While I was in the territory, I went ahead and cleaned up some single
vs. double quote hygiene in the file.

Fix computation of primitive array widths.

The code was comparing class pointers, but the class objects for arrays
of primitives are initialized on demand.  If the class wasn't yet
instantiated, the array width code was returning a default value of 4.
This meant the "write values to an array of longs through the unsafe
methods" code was actually scribbling on the wrong part of the array,
which went unnoticed until recently.  (The new-ish ldrexd/strexd code
requires 64-bit alignment.)

We now use the existing array element width computation function.  The
code needed a bit of rearranging since it expected an instance of the
class rather than the class.

Bug 3023981.
