If the debugger is enabled while streaming compilation is happening, we won't correctly tier down to Liftoff. This is because during streaming compilation, we always compile for no debugging. Fixing that is a bit tricky, since when the debugger is enabled, functions can either already have finished compiling, or they are currently being compiled, or their wire bytes are not received yet. Instead of handling this correctly while streaming compilation is running, we just recompile the whole module with Liftoff after streaming compilation finished. For testing this, we use the existing tests for async compilation, and enable --wasm-test-streaming, which compiles via the streaming decoder even in the async compilation case.

The lowering for anytrue was assuming that the input nodes are all integers. The regression test added in https://crrev.com/c/2194471 calls anytrue with float operands, this was causing the lowering to generate cmpl instructions with a float register and an immediate, which is wrong. The fix is to use GetReplacementsWithType on the input nodes, but only if the input were floats, since we use Word32Equal. Drive-by clean up of comments in the aforementioned regression test.

The codegen uses a bunch of vpmax to try and keep set bits around. The datatype for vpmax does not need to change for each instruction, since vpmax U32 will persist set bits just as well. This simplifies the instruction sequences for S1x8 and S1x16 anytrue. I added a test to check a special case when a f64x2 contains -0.0 (top bit set). A previous attempt to optimize codegen used floating point compare, which does not distinguish between 0.0 and -0.0. So -0.0 will compare equals to 0.0, and incorrect return 0 for anytrue.
