Currently, feedback vectors are allocated on a fixed budget of 1024. In some cases it might be beneficial to allocate feedback vectors based on invocation count rather than fixed budget. For example, if we have a large function that is only run once. This cl adds an option to use interrupt budget based on the bytecode size. It kind of mimics invocation count. We would allocate feedback vectors early when we have loops which is also required. This flag is turned off by default. In followup cl, we will enable it and if the memory / performance tradeoff is good we might make it default.

ref.test, ref.cast, and br_on_cast instructions all need to type check a value against an rtt. With new classification functions on the horizon, the wasm-compiler code needed to be refactored to avoid excessive code duplication. This CL factors out a function TypeCheck that takes as arguments a set of three callbacks functions: a conditional success, a conditional failure, and a negated conditional failure. Each of RefTest, RefCast, and BrOnCast call TypeCheck with a different set of callbacks.

All wasm code has an initial ref count of 1, in the expectation that it will be added to the code table. When the code is removed from that table, the ref count will be decremented. Stepping code (and also other code under special circumstances) will not be added to the code table though. Hence the ref count will never be decremented below 1, and the code will never be garbage-collected. This CL fixes this, by decrementing the ref count if the code is not added to the code table. Note that the code will only be collected if no isolate is currently using it, so it won't be collected while still in use for stepping.

Start nodes for JS functions have the following Parameter node value outputs: closure, ...args_including_receiver, new_target, argc, context This CL adds helper functions for these. There's two interesting gotcha's: - Each Parameter node is associated with an index, starting at -1. Value output indices obviously start at 0, so there's an off-by-one between the value output of the Parameter node, and the Parameter node's associated index. - CSA/Torque graphs use different Start node layouts, yet these are not reflected in compiler logic. There's potential for confusion here. The two layouts should be unified or made explicit. Finally, tests create Start nodes with arbitrary layouts. This blocks removal of methods marked _MaybeNonStandardLayout. In an ideal world, the parameter index would equal the start node output index, and the layout of all Start nodes would be equal. Future work..

Multi byte values get stored on native host order when arrays are being constructed, however as Wasm is LE enforced, they get reversed on BE machines during simd load. This causes incorrect values loaded into vector registers. This CL will force mask elements to be saved in byte sizes to eliminate endianness issues.
