[vm] Enable type stubs based type checks in JIT mode for some types. Relanding 4be50d6fa1737dcb8402041ecb7334e5a34ba3a1 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%.
