[GlobalOpt] Do not fold away addrspacecasts which may be runtime operations (#153753) 
Specifically in the context of the once-stored transformation, GlobalOpt
would strip
all pointer casts unconditionally, even though addrspacecasts might be
runtime operations.
This manifested particularly on CHERI targets.

This patch was inspired by an existing change in CHERI LLVM
(91afa60f17),
but has been reimplemented with updated conventions, and a testcase
constructed from scratch.
