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

Differences:
- Handle one more flags conflict in variants.py.
- Disallow %VerifyType without --concurrent-recompilation.

Extend type assertions to all types covering JavaScript values.
This is achieved by allocating type representations on the heap using
newly defined HeapObject subclasses. To allocate these in the compiler,
we disable concurrent compilation for the --assert-types flag for now.
Fix two type errors that came up with the existing tests:
1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of
OtherObject.
2. OperationTyper::NumberToString(Type) can type the result as the
HeapConstant Factory::zero_string(). However, NumberToString does
not always produce this string. To avoid regressions, the CL keeps
the HeapConstant type and changes the runtime and builtin code to
always produce the canonical "0" string.
A few tests were failing because they check for truncations to work
and prevent deoptimization. However, AssertType nodes destroy all
truncations (which is by design), so these tests are incompatible
and now disabled for the assert_types variant.
Drive-by fix: a few minor Torque issues that came up.

1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

The mentioned asserts did not work properly with interpreted and turbofanned functions.
To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value.
This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(),
isOptimized(fun), etc.

This CL adds --crankshaft and --no-always-opt flags to the tests that use
assertOptimized() and assertUnoptimized() respectively.
This CL also adds presubmit checks that ensure that tests have the proper
flags set.
