Many methods which currently receive a {ValueType} really just need to know the register class. Thus introduce a {RegClass} enum with values {kGpReg} and {kFpReg}, and change some methods to use it. For most methods, only the {kGpReg} case is implemented for now. Support for {kFpReg} will be added later.

This CL adds the --trace-wasm-lazy-compilation flag, to track which function is being compiled, and how many locations in the caller and in function tables are actually being patched. It seems that we currently don't patch the caller correctly when calling through wasm-to-wasm stubs, and this tracing helps to find the issue. Drive-by: Fix order and location of macro undefs.

Properly handle known JSBoundFunction instances as targets to JSConstruct by inlining the construction of the eventual target. Also if the target is the result of a JSCreateBoundFunction call, where we can also fold the construction and construct the bound target function directly instead. This addresses half of the TODO in the JSConstruct lowering in the JSCallReducer where so far we didn't handle bound functions.

In a recent CL I introduced module-level CodeSpaceMemoryModificationScopes, which means that the number of CodeSpaceMemoryModificationScopes which are opened aside from TurboFan compilation is not linear in the number of functions anymore. In that CL, however, I did not remove scopes which became obsolete. This CL removes now these obsolete scopes, and introduces some scopes where shared code was used from outside the compilation logic.

The flag --enable-tracing can be used to measure how much time is spent in a scope. In d8 this flag did not work properly for the following reasons: * The tracing file is not written when the JavaScript code calls quit(). * The tracing file is not written when the JavaScript code throws an uncaught exception, except if the --throws flag is passed to d8. The reason for these two issues is that both call Shell::Exit(), which end d8 immediately without calling any destructors. In addition I moved in a recent CL the destruction of the platform after the destruction of the file handle for the tracing file. Thereby the tracing file did not get filled with content even destructors were executed. With this CL I also call the destructors of the platform and of the file handle in the Shell::Exit() function. For this I make Shell::Exit() platform independent and let it call the platform dependent Shell::OSExit() at the end.

In order to implement CacheState merging correctly, we need to know at least the register type to be used for each stack slot. For stack slots, this is not stored currently. Since there is enough space available in the VarState anyway, we just always store the full type, which will allow also for other optimizations like not always spilling and filling the full 8 bytes.

This adds a fast path that avoids the runtime transition for JSArray source arguments with {packed,holey} {smi,double} elements kinds. The fast path currently calls straight into C and copies there using elements accessor logic. Local tests show a 4x speedup when copying from 1-element JSArrays. As the source array becomes larger, the time spent copying elements begins to dominate.
