      [wasm-simd] Fix i64x2 splat isel on ia32 · 0e06c3bb
      Ng Zhi An authored 
      In the non-avx case, we are incorrectly using DefineSameAsFirst, which
is wrong, since operand0 is a 32-bit register, but the output should be
a simd register. This error was caught by running the test with flag:
--no-enable-avx, leading to a register allocator verifier failure.

Drive by cleanup to remove duplicate cases for avx and see in i64x2 replace
lane.

      PPC/s390: Reland^2 "[runtime] Move Context::native_context to the map" · 36ab93d8

Original Commit Message:

    This is a reland of c7c47c68.

    This makes TSAN happy in addition to:

    Previously I presumed that the context read from a frame in the profiler was
    a valid context. Turns out that on non-intel we're not guaranteed that the
    frame is properly set up. In the case we looked at, the profiler took a
    sample right before writing the frame marker indicating a builtin frame,
    causing the "context" pointer from that frame to be a bytecode array. Since
    we'll read random garbage on the stack as a possible context pointer, I made
    the code reading the native context from it a little more defensive.

    Original change's description:
    > [runtime] Move Context::native_context to the map
    >
    > Remove the native context slot from contexts by making context maps
    > native-context-specific. Now we require 2 loads to go from a context to the
    > native context, but we have 1 field fewer to store when creating contexts.
