This reverts commit bab2b3de.
Reason for revert:
A fixed clang version has been rolled in, so this flag should no longer
be necessary.
Original change's description:
> Vulkan: Disable global merge for volk
>
> This optimization pass breaks the build by exporting volk's internal
> binding symbols from libGLESv2.so. Since the test binary also links
volk,
> this causes a SEGV as the wrong (uninitialized) function pointer is
> called.
>
> This is an LLVM bug and will be fixed upstream:
> https://reviews.llvm.org/D73235
>
