Previously `number(boolean)` casts were converted to a ternary during
IR generation, and `boolean(number)` casts caused an error.
Metal and GLSL should support this cast as written. SPIR-V needed a
little bit of logic to handle converting the boolean to a number via
OpSelect.

The new unit test demonstrates load/store reordering is error-prone.
At head we're allowing loads from a given pointer to reorder later than
a store to that same pointer, and boy, that's just not sound. In the
scenario constructed by the test we reorder this swap,
x = load32 X
y = load32 Y
store32 X y
store32 Y x
using schedule() (following Op argument data dependencies) into
y = load32 Y
store32 X y
x = load32 X
store32 Y x
which moves `x = load32 X` illegally past `store X y`.
We write `y` twice instead of swapping `x` and `y`.
It's not impossible to implement that extra reordering constraint: I
think it's easiest to think about by adding implicit use edges in
schedule() from stores to prior loads of the same pointer. But that'd
be a little complicated to implement, and doesn't handle aliasing at
all, so I decided to ponder on other approaches that handle a wider
range of programs or would have a simpler implementation to reason
about. I ended up walking through this rough chain of ideas:
0) reorder using only Op argument data dependencies (HEAD)
1) don't let load(ptr) pass store(ptr) (above)
2) don't let any load pass any store (allows aliasing)
3) don't reorder any Op that touches memory
4) don't reorder any Op, period.
This CL is 4). It's certainly the easiest and cheapest implementation.
It's not clear to me that we need this scheduling, and should we find we
really want it I'll come back and work back through the list until we
find something that meets our needs.
(Hoisting of uniforms is unaffected here.)

Fixes terminology inside the generator to correctly use 'arguments'
rather than 'parameters'. Retains the caller-supplied argument span, so
that generateCode can push changes to 'out' and 'inout' parameters back.
Adds a useful helper function for getting a named function from a
Program.
All of this is used more extensively in upcoming CLs that migrate
interpreter unit tests (and particles) to SkVM.

The code didn't take into account that x and y might be different types.
(This bug was not actually harmful; type coercion allowed the code to
compile even with the wrong type. The float would be silently splatted
into a vec and the rest of the code would work as-is.)

Implement support for text 'rotate' attribute:
https://www.w3.org/TR/SVG11/text.html#TSpanElementRotateAttribute.
Unlike other character-positioning attributes (x/y/dx/dy), rotate
- is not cumulative
- only applies to its respective node scope (does not affect other
fragments in the current chunk)
- has different padding semantics: if there are fewer rotate
values than characters, the remaining characters use the last
specified value from the closest ancestor
To the last point, we now have to discriminate three states:
- unspecified (default -> 0)
- explicit value for the given character index
- implicit value (last value in the closest ancestor)
Local implicit values override implicit ancestor values -- but not
explicit ancestor values.
High level changes:
- plumb 'rotate' attribute
- expand per-character position info (ShapeBuffer) to include rotation
- expand per-glyph position info (RunRec) to include rotation
- expand PosAttrs to include rotation and add specific inheritance
rules (see above)
- pass computed rotation values to RSX blob buffers

While it is not often that moving an SkAutoDescriptor saves much, it
being non-movable prevents other classes which use it (like SkStrikeSpec)
from being default movable.
In general types with a copy constructor but an explicitly deleted move
constructor are generally not a good idea in C++.

This makes the function appear to be undefined, which inhibits inlining
