d43ad8738c array-search: Add helpers to search for a byte in array
The radix tree code will need the code to find 8-bit value
in an array of some fixed size, so here are the helpers.

Those that allow for SIMD implementations are such for x86_64

TODO: Add aarch64

c41905e986 utils: array-search: deinline, working around clang bug
Clang has a bug processing inline ifuncs with intrinsics[1].
Since ifuncs can't be inlined anyway (they are always dispatched
via a function pointer that is determined based on the CPU
features present), nothing is gained by inlining them. Deinlining
therefore reduces compile time and works around the clang bug.

Closes #7358
