You could reference bfe, sbfx and ubfx instructions in aarch64.md
to see how to write the insert and extract bit with RTL code.

Just use generic RTL code for bset and bclr is fine, you could
reference bitmanip.md

Agreed.  And as a general principle if we can reasonably express the 
semantics of an instruction with RTL, we generally should.  Doing so 
gives the optimizers a chance to improve stuff.

I haven't looked at the patches, but the same might apply to the 
extractions & insertions, though there's more complex in that there's 
multiple implementations and I suspect some general cleanups would 
likely be necessary for that to work.  We started to look at it a bit, 
but concluded there were bigger fish to fry.
