Move shader register setup to SkRasterPipelineBlitter.

We've been seeding the initial values of our registers to x+0.5,y+0.5,
1,0, 0,0,0,0 (useful values for shaders to start with) in all pipelines.
This CL changes that to do so only when blitting, and only when we have
a shader.

The nicest part of this change is that SkRasterPipeline itself no longer
needs to have a concept of y, or what x means.  It just marches x
through [x,x+n), and the blitter handles y and layers the meaning of
"dst x coordinate" onto x.

This ought to make SkSplicer a little easier to work with too.

Get rid of level of indirection, noticed by VC++ 2017 bug

When building Chrome with VC++ 2017 the QuickFDot6Inverse::table pointer
is initialized to zero. This is certainly a bug, and it has been
reported to the VC++ team. But, the table pointer appears to be
unnecessary. Changing the code to reference the array directly should
give identical or perhaps even better code.

The change to the array indexing code is as follows:

- return table[x];
+ gFDot6INVERSE[kInverseTableSize + x];

This looks like a step backwards, but it isn't. 'table' is a pointer.
So, by default the compiler will load this pointer and then load the
value from the array. gFDot6INVERSE is an array, not a pointer. This
means that the adding of kInverseTableSize is trivially done at
compile time, and there is no loading of a pointer - only one data
segment memory access is needed.

The compiler may have realized that this optimization was ready before,
but now it is more trivial. And, this works around the VC++ 2017 bug so
that Chrome with VC++ 2017 will launch.

Fix performance issue and compute intersections more often.

(This CL also turned on Analytic AA for concave paths by removing SK_SUPPORT_LEGACY_AAA flag.)

Performance:
The SK_ALWAYS_INLINE was restored because it could bring 30%-50% speedup
in certain convex cases (e.g., fill_big_triangle). We also have to
reduce the number of branchings in the concave code path to enable such

SkSplicer: lowp hacking

Add lowp variants for most stages in SkSplicer.  These double the number
of pixels handled by representing each channel with 16 bits, ranging from
0x0000 as 0 to 0x8000 as 1.  This format lets us use the Q15 multiply
instructions available in NEON and SSSE3 at full register width, with
a little platform-specific fix up to smooth over the fact that these
aren't quite Q15 values.

When a lowp stage is unavailable, the entire pipeline upgrades to
floats.  So by simply not implementing sRGB, f16, matrix multiplication,
etc, we naturally express that they're best handled with floats.

These lowp stages ended up different enough that I've found it clearer
to have them live in their own files, noting where they differ from the
float stages.  HSW, aarch64, and armv7 are all supported.

I've seen very good things performance-wise on all platforms.

Added constant propagation and better variable liveness tracking to skslc.

This allows skslc to track the values of variables with constant
values across multiple statements and replace variable references with
constant values where appropriate.

The improved liveness tracking allows skslc to realize that a
variable is no longer alive if all references to it have been
replaced. It is not yet doing much with this information; better
dead code elimination is coming in a followup change.

Use fixed size buffer for RLE bmps

An RLE bmp reports how many bytes it should contain. This number may be
incorrect, or it may be a very large number. Previously, we buffered
all bytes in a single allocation. Instead, use a fixed size buffer and
only read what fits into the buffer. We already have code to refill the
buffer if there is more data, so rely on that to keep reading.

Choose an arbitrary size for the buffer. It is larger than the maximum
possible number of bytes we need to read at once.

Add a test with a test image that reports a very large number for
the number of bytes it should contain. With the old method, we would
allocate 4 gigs of memory to decode this image, which is unnecessary
and may result in OOM.
