The new DCHECK fires when the tier was set to {kNone}, which was the
case for wrappers.
Since the compiler is only interesting for proper Wasm functions, we
keep the DCHECK but only print the compiler for code objects that
represent actual Wasm functions.

These tests require --validate-asm, which is available only on
WebAssembly enabled builds. This was causing problems
on https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux%20-%20arm%20-%20sim%20-%20lite/15320/overview.

Moving them into regress/asm, the status file automatically skips these
tests if WebAssembly is not enabled.

This moves all asm.js tests (tests that use "%IsAsmWasmCode") into a
separate directory. This will make it easier to skip them all in the
v8_enable_webassembly=false configuration.
