Subject: [PATCH] FELightningNEON.cpp fails to build, NEON fast path seems
unused https://bugs.webkit.org/show_bug.cgi?id=241182
Reviewed by NOBODY (OOPS!).
Move the NEON fast path for the SVG lighting filter effects into
FELightingSoftwareApplier, and arrange to actually use them by
forwarding calls to applyPlatformGeneric() into applyPlatformNeon().
Some changes were needed to adapt platformApplyNeon() to the current
state of filters after r286140. This was not detected because the code
bitrotted due to it being guarded with CPU(ARM_TRADITIONAL), which does
not get used much these days: CPU(ARM_THUMB2) is more common. It should
be possible to use the NEON fast paths also in Thumb mode, but that is
left for a follow-up fix.
