93ce79dba4 drop SkTextBlob alignas(void*), align in Builder manually
GCC can't handle SK_API and alignas() next to each other,
tested up through GCC 8.1.

Instead, just align up the area we allocate for the SkTextBlob.

015c899d34 port most SkAtomic<T> to std::atomic<T>
The only SkAtomic<T> left are the ones overriding the default memory
order in SkPath.  I think I'd like to try switching them to std::atomic
too, but in another CL.

Trim unused APIs in SkAtomics.h.

475c5e93fe turn on alignment sanitizer
This sanitizer checks for overaligned reads and writes,
or put another way, use of underaligned pointers.

This usually happens when you cast, e.g. char* to int*
without checking that the char* is 4-byte aligned.  Each
of the changes under src/ fixes something just like that.

The unusual setup for tools/xsan.blacklist is there to
force a rebuild whenever tools/xsan.blacklist changes.
I spent a good few minutes debugging rebuilds not happening
this morning, perhaps from some strange ccache interaction.

Align SkTextBlobs as void* (today they're just 4-byte) so the
SkTextBlob::RunRecords we put after them in SkTextBlobBuilder
buffers are properly aligned (for the SkTypeface* inside).

There's no obvious error in void SkRRect::computeType(),
but one bot seems to have seen some sort of issue with

    SK_AT_SCOPE_EXIT(SkASSERT(this->isValid()));

I can't reproduce it locally, so I'm just going to unroll it.

e12a090a63 make some textblob builders private for now
Move SkTextBlobBuilder::allocRunText* to private: for the time
being, to reduce the documented interface footprint.

No code is deleted; the functions may be restored when a
client is ready to call them.

Also, add SkTextBlob::MakeFromString to complement
SkTextBlob::MakeFromText.

785586af7d remove unused serialization in textblob
The SKTextBlob serialization code that is tested by Skia is
unused by Chrome. The serialization code that is
used by Chrome is untested by Skia.

Remove the unused code; test the used code.

The code path introduced nearly a year ago,
likely for slimming paint, attempts to make
text blobs smarter by allowing the reuse of typefaces.

Maybe there needs to be a Chrome bug / feature
request to use this?

If if turns out there is no interest to do so,
This CL aligns used interfaces with tests.

a93a14a998 Convert NULL and 0 to nullptr.
This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

b47cd4b3d6 Use SkNVRefCnt for a couple common types.
These types are ref-counted, but don't otherwise need a vtable.
This makes them good candidates for SkNVRefCnt.

Destruction can be a little more direct, and if nothing else,
sizeof(T) will get a little smaller by dropping the vptr.

3c196def91 Souped-up SkTextBlob.
Refactored text blob backend for improved performance: instead of using
separate buffers for runs/positions/glyphs, everything is now packed in
a consolidated slab (including the SkTextBlob object itself!).

Benefits:

 * number of allocations per blob construction reduced from ~4 to 1
   (also minimizes internal fragmentation)
 * run record size reduced by 8 bytes

This takes the blob construction overhead down to negligible levels
(for the current Blink uncached textblob implementation).

Unfortunately, the code is much more finicky (run merging in
particular) -- hence the assert spree.

Multi-run blobs are vulnerable to realloc storms but this is not a
problem at the moment because Blink is using one-run blobs 99% of the
time. Will be addressed in the future.
