Merge commit 16a1ef86cbc5 from llvm-project (by David CARLIER):

[compiler-rt] remove hexdump interception. (#79378)

a freebsd dev member reported a symbol conflict and intercepting this
had little value anyway.

This is one part of fixing the WITH_ASAN build. Some executables in the
base system define their own hexdump() symbol, which would otherwise
conflict with the ASan-intercepted one.
