Move more logic to shouldTailDuplicate and only duplicate regular bb before
...
register allocation if it has a indirectbr or if we can duplicate it to
every predecessor.
This fixes the SingleSource/Benchmarks/Shootout-C++/matrix.cpp regression but
keeps the previous improvements to sunspider.

lit support for REQUIRES: asserts.
...
Take #2 . Don't piggyback on the existing config.build_mode. Instead,
define a new lit feature for each build feature we need (currently
just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define
this feature within test/lit.site.cfg. This doesn't require any lit
harness changes and should be more robust across build systems.
