The hard-coded timeout in the test is so near, that e.g., adding DCHECKs pushes the test over the limit. The test is ran with dcheck_always_on=true. We shouldn't do any performance testing with dcheck_always_on=true; this creates the wrong incentive to not add DCHECKs (or in this case, CLs which add more DCHECKs or cause more DCHECKs to be hit cannot land at all).

The DCHECK was incorrect. This new API method can be called from any debug mode since the embedder does not know which mode we are in. It should only apply the side effect logic when the mode is kSideEffects.

Stubs and builtins are very similar. The main differences are that stubs can be parameterized and may be generated at runtime, whereas builtins are generated at mksnapshot-time and shipped with the snapshot (or embedded into the binary). My main motivation for these conversions is that we can generate faster calls and jumps to (embedded) builtins callees from (embedded) builtin callers. Instead of going through the builtins constants table indirection, we can simply do a pc-relative call/jump. This also unlocks other refactorings, e.g. removal of CallRuntimeDelayed.

In the process, rename Boolean constants (i.e. JavaScript constants), to 'True' and 'False'. This uncovered a bug in the internal handling of True/False labels was fixed (they shouldn't be Values and Torque shouldn't conflate Labels with other Declarables, throwing exceptions when they're improperly used in the wrong context). Furthermore, the internal labels used for True and False for if statements have been renamed so that they can't be aliased from user Torque code.

In preparing for adding trap-based bounds checking to Windows, this change refactors the code to separate the platform-specific portions from that which can be shared between platforms. Internally, we've renamed `RegisterDefaultSignalHandler` to `RegisterDefaultTrapHandler` to more accurately represent the difference in terminology between Linux (signals) and Windows (exceptions). The external API is left the same so as not to break downstream clients. This CL is primarily to make room for Windows support. Future CLs will begin adding support for Windows. This is a reincarnation of https://crrev.com/c/626558.

Torque expressions of type constexpr are evaluated at compile-time rather than runtime. They are backed by C++ types rather than TNode<X> types, so the macro functions that are called by generated C++ code expect values to be computed when the snapshot is generated rather than by TurboFan-generated code. Specifically, "if" statements can have a constexpr modifier. With this modifier, a type of "constexpr bool" is expected rather than "bool", and in that case instead of generating a CSA BranchIf, it generates a C++ "if (<bool expression>)" that generates code for only the true or false path based on the bool value at torque-execution (compile time) rather than generating both paths (including inserting phi nodes for variables modified on either branch at the re-merge at the end of the if) and dynamically dispatching to the true or false path during d8/Chrome/node.js execution (runtime) using a CSA BranchIf.

This method is intended for use by code caching as follows: 1. The module is compiled (and perhaps instantiated). 2. The embedder fetches and stores the module's unbound script (i.e. the shared function info). 3. Module evaluation, maybe triggering lazy compilation. 4. Generated code for the module (which hangs off the shared function info) is inserted into the code cache. Subsequent module loads can load from the code cache prior to evaluation.
