Revert "src.opts.mk: Default LLVM_ASSERTIONS off"

Browse Source 
Enabling and disabling LLVM assertions changes the ABI. There have
been multiple reports on the freebsd-current@ mailing list of broken
'cc'.

Out of caution, you may wish to do a clean build while crossing this
commit after building the reverted commit if you do not set
LLVM_ASSERTIONS in your src.conf.

Discussed with:	kevans, jrtc27
