[WebAssembly] Add shuffles as an option for lowering BUILD_VECTOR
When lowering a BUILD_VECTOR SDNode, we choose among various possible vector
creation instructions in an attempt to minimize the total number of instructions
used. We previously considered using swizzles, consts, and splats, and this
patch adds shuffles as well. A common pattern that now lowers to shuffles is
when two 64-bit vectors are concatenated. Previously, concatenations generally
lowered to sequences of extract_lane and replace_lane instructions when they
could have been a single shuffle.

[WebAssembly] Remove unimplemented-simd target feature
Now that the WebAssembly SIMD specification is finalized and engines are
generally up-to-date, there is no need for a separate target feature for gating
SIMD instructions that engines have not implemented. With this change,
v128.const is now enabled by default with the simd128 target feature.

Reland "[WebAssembly] Emulate v128.const efficiently""
This reverts commit 432e4e56d3d2, which reverted 542523a61a21. Two issues from
the original commit have been fixed. First, MSVC does not like when std::array
is initialized with only single braces, so this commit switches to using the
more portable double braces. Second, there was a subtle endianness bug that
prevented the original commit from working correctly on big-endian machines,
which has been fixed by switching to using endianness-agnostic bit twiddling
instead of type punning.

[WebAssembly] Emulate v128.const efficiently
v128.const was recently implemented in V8, but until it rolls into Chrome
stable, we can't enable it in the WebAssembly backend without breaking origin
trial users. So far we have been lowering build_vectors that would otherwise
have been lowered to v128.const to splats followed by sequences of replace_lane
instructions to initialize each lane individually. That produces large and
inefficient code, so this patch introduces new logic to lower integer vector
constants to a single i64x2.splat where possible, with at most a single
i64x2.replace_lane following it if necessary.
Adapted from a patch authored by @omnisip.

[WebAssembly] v8x16.swizzle and rewrite BUILD_VECTOR lowering
Summary:
Adds the new v8x16.swizzle SIMD instruction as specified at
https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md#swizzling-using-variable-indices.
In addition to adding swizzles as a candidate lowering in
LowerBUILD_VECTOR, also rewrites and simplifies the lowering to
minimize the number of replace_lanes necessary rather than trying to
minimize code size. This leads to more uses of v128.const instead of
splats, which is expected to increase performance.
The new code will be easier to tune once V8 implements all the vector
construction operations, and it will also be easier to add new
candidate instructions in the future if necessary.

[WebAssembly] Optimize BUILD_VECTOR lowering for size
Summary:
Implements custom lowering logic that finds the optimal value for the
initial splat of the vector and either uses it or uses v128.const if
it is available and if it would produce smaller code. This logic
replaces large TableGen ISEL patterns that would lower all non-splat
BUILD_VECTORs into a splat followed by a fixed number of replace_lane
instructions. This CL fixes PR39685.
