fbeaeb26ef [wasm] Remove test-only {RelocInfo::JS_TO_WASM_CALL}.
The relocation mode in question was by now only used in tests to model a
wrapper call from wrapper code (on the GC'ed heap) to a non-movable wasm
code object. Instead of using a special relocation mode, we switch to
using the existing {EXTERNAL_REFERENCE} mode similar to other static C++
functions called from generated code.

cb8d93e13d Fix -Wdefaulted-function-deleted warnings
This is part of clean-up for a new Clang warning that we'd like to

a2139261ca [cleanup] Remove empty and deprecated BASE_EMBEDDED macro
The macro has been deprecated since 2016, and it keeps confusing me, so
let's just remove it completely from the code base.

9d341c4c18 [ia32] Fix off-heap trampoline handling
This fixes several issues related to off-heap trampoline handling on
ia32.

Unlike other architectures, ia32 uses a pc-relative call/jump for the
off-heap trampoline. That means we cannot skip reloc info emission,
and we need to relocate when the buffer grows during code generation.

Finally, inlined trampolines must not clobber and thus also need to
use a pc-relative call/jump.

Drive-by: Use PreserveRootIA32 config only for whitelisted builtins to
build successfully by default.

e5e30b3463 [wasm] Ensure all wasm runtime stubs are PIC
Some builtins, so-called wasm runtime stubs, are copied off-heap to
ensure reachability through near jumps. These builtins must be
individually position-independent. In particular, they may not contain
pc-relative calls to other builtins.

Drive-by: Set hard_abort mode for all wasm runtime stubs to avoid Abort
calls.
