To be consistent with the all the other tiers and avoid confusion, we
rename --opt to ---turbofan, and --always-opt to --always-turbofan.

Bytecode flushing can make tests using assertOptimized flaky if the bytecode is
flushed between marking and optimization. It can also be flaky if the feedback vector
is collected before optimization. To prevent this, a new %PrepareForOptimization
runtime-test function is added that hold onto the bytecode strongly until it is
optimized after being explicitly marked for optimization by %OptimizeFunctionOnNextCall.

The CheckSmi in String.fromCodePoint() is unnecessary and even leads to
unnecessary deoptimizations, since the CheckBounds already does the
right thing, plus it also handles HeapNumbers (in Signed32 range) and
properly identifies zeros.
