Relanding 4be50d6fa1 with fixes to DBC
and location summaries: AssertAssignable must save FPU registers.
For now we are limiting this to type checks against type parameter types.
In Dart 1 mode Dart2JS compiles itself in 28s when running from source
and in 23s when running from ideal app-jit snapshot (trained on the
same workload).
Before this change in Dart 2 mode numbers were 51s and 57s respectively.
After this change in Dart 2 mode numbers are 38s and 32s. Meaning
that regression is reduced by 50%.
