When starting a nested loop, we can't rely on the condition mask to keep
dead lanes dead, because of conditional breaks/continues that may have
happened earlier. So always narrow the loop mask by inheriting the
previous one.

Slightly sharper, but far easier to hold:
- Remove Value union from interface, everything is a 32-bit
value type, or a collection thereof.
- Collapse to one version of Run (that takes count), and make
it a member on ByteCode.
- Similarly, move disassemble to ByteCodeFunction.

This converts the SkSL interpreter to operate in SIMT fashion. It handles
all the same features as the previous scalar implementation, but operates
on N lanes at a time. (Currently 8).
It's modeled after GPU and other parallel architectures, using execution
masks to handle control flow, including divergent control-flow.

Interpreter is now just a namespace with Run and Disassemble. This hides
all of the implementation details. In addition, the interpreter only used
the Program because of a few details in FunctionDeclarations - scrape that
when constructing a ByteCodeFunction, and we don't need to keep the entire
Program alive, just the ByteCode. Adjust tests to ensure that this works.

Per GLSL, constructing a matrix from a scalar produces a matrix
with the scalar value along the diagonal, and zero elsewhere.
Constructing a matrix from another matrix copies the overlapping
values, and fills in the remainder with the identity matrix.
Doing either of these with existing opcodes was going to be quite
verbose and tricky, so I just made new opcodes.
I've also got some (currently disabled) test cases for other
matrix behavior, all of which fail in various ways today.

Avoids the need for a PushImmediate (which usually also required
a Nop for alignment) on every load/store. And it makes the codegen
for local vs. global identical, which simplifies the byte-code
generator in a few spots.
This means that places previously using DupDown now need something that
dupes the *top* N elements of the stack. Just use Vector + Dup, and
remove the (now unused) DupDown instruction.
Also add/implement kStoreSwizzleGlobal, which was the last missing
load/store op (and add a test case).

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.
