src.opts.mk: Default LLVM_ASSERTIONS off
This noticeably slows down the compiler execution and with the move to
pkgbase is one of the remaining differences that cannot be
administratively controlled; pkg kernels and malloc.conf(5) will allow
quickly testing a snapshot in a configuration closer to stable and
release branches.
dim@ notes that you need to set WITH_LLVM_ASSERTIONS in src.conf(5) if
you want to report an issue with LLVM.
Enabling WITH_LLVM_ASSERTIONS is also a consideration for CI and pkg
builders especially tracking main.
