In AVX, it is better to use the appropriate integer or floating point moves depending on which instructions produce/consume these moves, since there can be a delay moving from integer to floating point domain. On SSE systems, it is less important, and we can move movaps/movups which is 1 byte shorter than movdqa/movdqu. This patch cleans up a couple of places, and defines macro-assembler functions Movdqa, Movdqu, Movapd, to call into movaps/movups when AVX is not supported.

With https://crrev.com/c/2087396 we introduced a new CDP method `Debugger.executeWasmEvaluator()`, which we originally intended to use as the foundation for Debug-Evaluate on Wasm frames. However in the process of prototyping we learned that it is too costly and too inefficient to use WebAssembly modules here, and we switched to regular Debug-Evaluate with JavaScript instead (with a special debug proxy exposed that allows JavaScript to peak into the Wasm frame), since JavaScript is better suited for short-lived / short-running snippets and we don't need clang and wasm-ld then to generate these snippets. The JavaScript exposed debug proxy (as described in [1]) not only enables more powerful and flexible Debug-Evaluate for the DWARF C/C++ extension, but also serves as the basis for various aspects of the Basic Wasm Developer Experience. In order to pay down technical debt and to keep the maintenance overhead low, we should remove the initial prototype now, also to ensure that we don't accidentally attract other users of CDP to rely on this unsupported API (despite it being marked as "experimental").

JavaScript scopes are reported from inner-most to outer-most, while previously we would report WebAssembly frames from outer-most to inner-most.

When a 8x16 shuffle matches a 32x4 shuffle (every group of 4 indices are consecutive), and the first 2 indices are in the range [0-3], and the other 2 indices are in the range [4-7], then we can match it to a shufps. E.g. [0,2,4,6], [1,3,5,7]. These shuffles are commonly used to extract odd/even floats.

Optimize: - i32x4.widen_high_i16x8_s - i32x4.widen_high_i16x8_u - i16x8.widen_high_i8x16_s - i16x8.widen_high_i8x16_u These optimizations were suggested in http://b/175364869. The main change is to move away from palignr, which has a dependency on dst, and also the AVX version is 2 bytes longer than the punpckhqdq. For the signed and unsigned variants, we have slightly different optimizations. Unsigned variants can use an punpckh* instruction with a zero-ed scratch register, that effectively zero-extends. Signed variants use the movhlps instruction to move high half to low half of dst, then use packed signed extension instructions. The common fallback for these instructions is to use pshufd, which does not have a dependency on dst, but is 1 byte longer than the punpckh* instructions.
