  [WebAssembly] Fix tests and build on x86-64 Linux with BBQJIT
https://bugs.webkit.org/show_bug.cgi?id=253618

Reviewed by Yusuke Suzuki.

This patch first enables building of the BBQJIT on x86-64 Linux
platforms by adding a line in WebKitFeatures.cmake.

The rest of the patch fixes build issues with GCC.

  - GCC doesn't support std::fabsf so use std::fabs instead.
    (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79700)
  - GCC doesn't support explicit specialization in class scope so
    this patch uses a `if constexpr` workaround.
    (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85282)
  - Add RELEASE_ASSERT_NOT_REACHED to suppress warnings.
