f10535f6fa Fuse GrGLSLPrimitiveProcessor and GrGLSLGeometryProcessor ...
into a new GrGLSLGeometryProcessor. Since NVPR is no more this
distinction (between GLSL- Primitive and Geometry -Processor)
probably isn't needed/useful.

9d26af9a82 Fix testing of Runtime Effects with inlining enabled and disabled.
Previously, the act of painting a Runtime Effect was causing its helper
functions to get inlined, even if inlining was disabled during the
initial SkSL generation. This meant that the "NoInline" path was not
actually very effective.

1b843bdcb7 Fix up outdated tests.
Removed error tests which no longer test anything:
- UseWithoutInitialize...: we no longer track variable use-before-init.
- InlineDivideByZero: we no longer constant-fold the result of an
  inlined function call into its parent statement.
- Unreachable: we no longer report unreachable statements.

And fixed some minor test-case issues:
- StaticSwitchConditionalBreak: we still check this, but the function
  was being dead-stripped before this check could run. Renamed to main.
- OssFuzzXxxxx: these cases no longer report errors, but they are still
  valuable as regression tests; moved to `shared/`.

7df8d22c40 Do register allocation in GrResourceAllocator (take 2)
This lets us plan out the allocation of resources without
actually committing to the resulting plan. In the future,
the user will be able to do the register allocation, then
query the estimated memory cost, and either commit to
that allocation or try a different order of operations.

The difference between this and the original 286097 are that we sorted
fFinishedIntvls by increasing start instead of increasing end and we
use the GrUniqueKey.hash instead of the default crc hash.

bff24abab8 Disallow inlining a function with out-parameters.
It is difficult to do this both efficiently and correctly while honoring
GLSL semantics (which require the lvalues to be kept distinct, even when
they point to the same variable). We could make it work by making copies
of every out parameter in each direction (going in for inouts, and
coming out for outs and inouts).

However, this could be self-defeating if it makes it harder for the
driver to track variable lifetimes. Simply opting out of inlining these
functions entirely seems like the best tradeoff; let the driver optimize
them if it can, and we can enjoy reduced complexity in the SkSL inliner.

dc20847579 Disallow inlining functions containing early returns.
This allows us to remove 100 LOC from the inliner and is very unlikely
to affect any existing benchmark. We don't have any evidence to support
the idea that a one-iteration `for` loop with `continue`-based exits
will be any faster than a standard function call on any existing GPU.
Our fragment processors are generally written to avoid early returns,
in large part to avoid hitting this path.

This drastically impacts BlendEnum.sksl (which can no longer flatten out
a switch over every blend function in SkSL) but is otherwise a wash.

See: http://go/optimization-in-sksl-inliner suggestion 4(a)

f10eff363b Fix misdetection of dead global variables.
A global variable should be considered "dead" if it's never written and
never read. The previous code checked if it was never written OR never
read, which is not the same.

This would generate GLSL/Metal that didn't compile. In SPIR-V, it would
SkASSERT, then crash, during codegen. The fuzzer was able to detect the
SPIR-V issue, but it was wrong in all three cases.

9e476b798f Refactored SPIR-V RelaxedPrecision handling
The RelaxedPrecision decoration is now handled by nextId(), to make it
easier to see all spots where a RelaxedPrecision decoration might be
necessary. The goal of this initial refactor is not to actually fix the
issues with RelaxedPrecision decorations, but rather to lay the
groundwork for doing so in followup CLs.

The initial intent of this change was to not affect the SPIR-V at all,
saving modifications for followups, but there ended up being three kinds
of changes to the output:

1. Doing things at nextId() time rather than later means some
decorations move to an earlier spot in the output. This results in
diffs, but should not cause any behavioral changes.
2. We were incorrectly tagging bools as RelaxedPrecision in some
situations. By funneling things through fewer code paths, the refactor
would have caused this to happen in even more situations, and the code
responsible for the bug was being rewritten in this CL anyway, so it
seemed worth just fixing the issue as part of this change.
3. Funneling things through fewer code paths ended up adding
(correct) RelaxedPrecision modifiers to binary operations that had
previously been missing them. It seemed better to just let it happen
than to try to maintain bug-for-bug compatibility with the previous
approach.

fc4b9919d3 Force global initializers to be constant expressions
Prevents us from accepting code that can't be correctly transformed to
GLSL, like:

  uniform float x;
  float y = x;

(Previously, writing code like that in a runtime effect would
effectively produce the exact same code all the way through to GLSL, and
the driver would fail to compile it).

around GrVkGpu instead of GrVkTextures where I could to start the

ddcb4d94f9 In pipeline stage generator, never emit declarations for opaque types
This only affects fragmentProcessors (children) - and the backend SkSL
we're emitting should not contain those. We've just been silently
ignoring those declarations when converting to GLSL, MSL, etc.

e8b5a73b56 Remove extraneous line-breaks in generated GLSL/Metal code.
I ran into an issue in an upcoming CL which generated a particularly
ugly switch statement:

    switch (x) {
        default:
             discard;}

So I cleaned this up, and while resolving this issue, managed to improve
a bunch of existing codegen as well. The formatting change has been
split out to a separate CL since it impacts so many golden outputs.
