Revert "[vm] Enable type stubs based type checks in JIT mode for some types." This reverts commit 4be50d6fa1737dcb8402041ecb7334e5a34ba3a1. Reason for revert: Failures on SIMDBC64 and Analyzer bots. Original change's description: > [vm] Enable type stubs based type checks in JIT mode for some types. > > For now we are limiting this to type checks against type parameter types. > > # Performance improvements > > 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%. > > Issue https://github.com/dart-lang/sdk/issues/31798 > Issue https://github.com/dart-lang/sdk/issues/33257 > > Change-Id: I34bf5385a5cc3c7702dc281c6dfa89da85d3dde1 > Reviewed-on: https://dart-review.googlesource.com/57601 > Reviewed-by: Régis Crelier <regis@google.com> > Commit-Queue: Vyacheslav Egorov <vegorov@google.com> TBR=vegorov@google.com,kustermann@google.com,regis@google.com Change-Id: I85a30c962b0cd556310e19193f5993ab76ecf2e7 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/57840 Reviewed-by: Vyacheslav Egorov <vegorov@google.com> Commit-Queue: Vyacheslav Egorov <vegorov@google.com>
