then divides the input by its length using a bit of DSL. Since all the

We were emitting this at global scope (not in Globals). That would lead
to errors about the variable needing to be in the constant address
space. (You can see the result in ConstArray.metal - the old code was
invalid). Also, we were already making references use _globals, so the
code was double-wrong (or half-right, depending on your perspective).
After the core change, writeVarDeclaration was only used for local
scope, and writeModifiers never used the 'globalContext' parameter.
The removal of finishLine() changed every test output, unfortunately.

Aside from sqrt() and normalize(), we now optimize all the intrinsics
which take a single argument as input, and return that argument with
each of its components permuted as output.
This CL also introduces a minor restriction--we no longer optimize
intrinsics which evaluate to inf or nan, such as `inversesqrt(-1)`.
These will be left in the source as-is.

This CL only handles a subset of our intrinsics. In particular, it
avoids changing the behavior of `sqrt` as many of our tests use sqrt as
an optimization barrier.
The transcendental test inputs are intentionally kept very simple to
avoid putting numbers in the test outputs which could round differently
on various platforms and cause Housekeeper to complain.

There are two forms. Swizzle::Make supports components XYZW only;
Swizzle::MakeWith01 also supports the 01 components, and restructures
the zeros and ones into a constructor (as IRGenerator::convertSwizzle
has historically done). This means that once we are past the initial
IR generation stage, and we know that the 01 components have been
eliminated, we can avoid the extra 01-handling logic and just call
Swizzle::Make directly. This isn't a huge deal but it means that call
sites like the inliner can avoid some extra work that will never happen.

When SPIR-V generates function calls to an intrinsic, it assumes that
it can get a pointer to out-parameters referenced by the intrinsic.
This does not account for swizzled out-parameters; these are valid
lvalues, but do not work with getPointer().
The two intrinsics supported by SkSL which have an out-parameter are
frexp and modf, so these tests were fleshed out to trigger the error.
Neither of these are supported in ES2, though, so we cannot test them
via Runtime Effects.

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.)

4x4 was dividing a matrix by a scalar - this isn't allowed, multiply by
the scalar's inverse instead.
The types in the signature were derived from type.name(), which wasn't
applying the half->float re-mapping.
Finally, use raw strings so the resulting shader code isn't all crammed
on one line.

When we determine that a function only contains a single return
statement and it is at the top level (i.e. not inside any scopes),
there is no need to create a temporary variable and store the
result expression into a variable. Instead, we can directly replace
the function-call expression with the return-statement's expression.
Unlike my previous solution, this does not require variable
declarations to be rewritten. The no-scopes limitation makes it
slightly less effective in theory, but in practice we still get
almost all of the benefit. The no-scope limitation bites us on
structures like
@if (true) {
return x;
} else {
return y;
}
Which will optimize away the if, but leave the scope:
{
return x;
}
However, this is not a big deal; the biggest wins are single-line
helper functions like `guarded_divide` and `unpremul` which retain
the full benefit.

Previously, coercion between a signed type and an unsigned type was
treated as "no cost" because these types shared the exact same priority.
This meant that we couldn't choose the proper overload with function
calls that only differed in signed-ness, like:
void fn(int4 x);
void fn(uint4 x);
So we would always choose the int4 version since we encountered it
first. Now, we can choose the correct overload; signed types now have
a slightly elevated priority over unsigned types, allowing coercion
costs to work normally.
Also added some comments to `determineFinalTypes` while trying to see
if that needed some improvements as well, but this turned out to be
a red herring--it didn't need any functional changes.
