commit 41b072b646f1178d4b16db72a55e5e5510c8dd66
Author: Nico Weber <thakis@chromium.org>
Date: Fri Feb 09 21:02:27 2018

Prepare for -Wimplicit-fallthrough in ANGLE.

Disable the warning for flex-generated output, which contains
lots of intentional fallthrough.

Fixes a bug where GL_SAMPLE_ALPHA_TO_ONE_EXT would fall through
to GL_COVERAGE_MODULATION_CHROMIUM and hence behave like that.

Fixes a bug in the D3D9 state management where invalidating
DIRTY_BIT_POLYGON_OFFSET would also invalidate the stencil bits.

One somewhat common incorrect pattern in ANGLE is nested switch
statements that look like so:

  switch (a) {
    case a1:
      switch (b) {
        case b1:
          ...
          break;
      }
    case a2:
      ...
  }

The assumption here seems to be that the breakk exits the outer
case (here a1), while it in fact only exits the inner switch,
so that we fall through to a2.  In most places, I fixed this
by adding an explicit `break` after the inner switch.

This fixes a bug wher GL_PATH_JOIN_STYLE_CHROMIUM would fall through to
GL_PATH_MITER_LIMIT_CHROMIUM in validation (but since the join style
enum is always > 0, this happened to not have an effect in practice).

This also fixes 87 bugs in GetLoadFunctionsMap() where invalid
values would previously return an unrelated function map instead
of the empty load function map.

Author: Nico Weber <thakis@chromium.org>
Date: Thu Feb 15 18:54:20 2018

Enable -Wimplicit-fallthrough for ANGLE.

Also teach MSVC that ANGLE_CRASH() can't return.

Also fix instances of the warning in build configurations where
UNREACHABLE() can return (e.g. release without dcheck_always_on
or debug).

If the UNREACHABLE()s are truly unreachable, this change has
no behavior change.
