Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

This enables four different options in the compiler, described
below. I also added enough masks to satisfy RTCc when running
all GMs in both 8888 and gl configs.
---
/RTCc - Detects when a value is assigned to a smaller data
type and results in data loss. This happens even when casting.
Masking is required to suppress this.
/RTCs - Various stack-related checks, including uninitialized
data (by initializing locals to a non-zero value), array bounds
checking, and stack pointer corruption that can occur with a
calling convention mismatch.
/RTCu - Reports when a variable is used without having been
initialized. Mostly redundant with compile-time checks.
/guard:cf - This is more of a security option, that computes
all possible targets for indirect calls at compile time, and
verifies that those are the only targets reached at compile
time. Also generates similar logic around switch statements
that turn into jump tables.

The 8K table in SkFDot6Constants.cpp is only used by SkAnalyticEdge and
its unit test, so to help LTO trim this when SkAnalyticEdge isn't used,
move it to SkAnalyticEdge.cpp and delete the unit test. (I suspect the
table is never going to change.)
I've also moved setLine() out-of-line into SkAnalyticEdge.cpp to make
this work, and done a little bit of refactoring and renaming.

S16CPU is used only inside Skia, and only sparsely.
- SkRandom::nextS16() and nextU16() were used rarely enough
that it makes things simpler to get rid of them.
- SkAlphaBlend255() was unused outside tests.
- SkIntToFDot6() looks like it really wants to take an int.

- remove dead code
- rewrite float -> int converters
The strategy for the new converters is:
- convert input to double
- floor/ceil/round in double space
- pin that double to [SK_MinS32, SK_MaxS32]
- truncate that double to int32_t
This simpler strategy does not work:
- floor/ceil/round in float space
- pin that float to [SK_MinS32, SK_MaxS32]
- truncate that float to int32_t
SK_MinS32 and SK_MaxS32 are not representable as floats:
they round to the nearest float, ±2^31, which makes the
pin insufficient for floats near SK_MinS32 (-2^31+1) or
SK_MaxS32 (+2^31-1).
float only has 24 bits of precision, and we need 31.
double can represent all integers up to 50-something bits.
An alternative is to pin in float to ±2147483520, the last
exactly representable float before SK_MaxS32 (127 too small).
Our tests test that we round as floor(x+0.5), which can
return different numbers than round(x) for negative x.
So this CL explicitly uses floor(x+0.5).
I've updated the tests with ±inf and ±NaN, and tried to
make them a little clearer, especially using SK_MinS32
instead of -SK_MaxS32.
I have not timed anything here. I have never seen any of these
methods in a profile.

Use an inline function that does a normal shift. When built for the sanitizer, add casts so that the shift is unsigned.
Also make a few fixes to do unsigned shifts or avoid the shift altogether; and add an argument spec to some macros.

REPORTF(reporter, ("Foo test Expected %d got %d", x, y));

This change removes sk_stdint.h since it is only needed for vs2008 and earlier.
This change removes SK_MMAP_SUPPORT define since it is no longer used.
This change removes the stdio.h include from SkTypes.h since on many systems
this is a very large header, few Skia files actually use it, it is
available everywhere standard, and SkDebugf should be used instead.
After this change there is no need for external users to put Skia's
include/config into their own list of includes, saving the headache
of having two header files of the same name and sometimes getting the
wrong one depending on include order.
