[JSC] Unsound optimization in ReduceStrength regarding Int52-to-Int32
conversion pattern
https://bugs.webkit.org/show_bug.cgi?id=308722
rdar://171147977
Reviewed by Yijia Huang and Keith Miller.
The optimization is assuming that constant value's lower 12 bits are
zero, otherwise, addition can carry one bit. This patch ensures that
constant is not having lower 12 bits.

[CoordinatedGraphics] Handle buffer creation failures gracefully
https://bugs.webkit.org/show_bug.cgi?id=308541
Reviewed by Carlos Garcia Campos.
When swap chain fails to create buffers, currently it stores nullptr
render targets and hence breaks assumptions in few places.
The above leads to crashes when headless WPE platform is used with
EGLImage buffers and when DRM device is guessed wrong.
This change implements graceful handling of such buffer creation
failures and also adjusts the wrong assumption in one spot.
