This adds ExecutionContextDescription.uniqueId for a system-unique way to identify an execution context and supports it in Runtime.evaluate. This allows a client to avoid accidentally executing an expression in a context different from that originally intended if a navigation occurs while Runtime.evaluate is in flight.

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.

For pblendw and palignr, if AVX is supported, we can use the 3-operand AVX instruction, this can save us a move. Bug: v8:11270 Change-Id: Ifd837e29c76886a3008bc63c17d4a68bc6aae364 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2596578Reviewed-by:

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.

Couple of optimizations for v128.bitselect on both ia32 and x64. 1. Remove an extra movaps when AVX is supported, since we have 3-operand instructions 2. Tweak the algorithm from: xor(and(xor(src1, src2), mask) src2) To: or(and(src1, mask), andnot(src2, mask)) It is easier to read and understand, and also eliminate a dependency chain (on kScratchDoubleReg) in the older algorithm. 3. Use integer forms of the logical ops. Older processors have higher throughput on these, compared to the floating point ops. However, the integer forms are 1 byte longer, so on SSE, we stick to the floating point ops. For AVX, this reduces instruction count from 9948 to 9868.
