[bazel] Compile V8 with bazel Command to build: `bazel build :d8` Caveats: - Needs clang - Only supports x64 on Linux - Bare V8: no Wasm and no ICU - Still needs GN to generate inspector files Bug: v8:11234 Change-Id: I6d01fecff5fba5c3582995d071692e5c6c6c6310 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2960949 Commit-Queue: Victor Gomes <victorgomes@chromium.org> Reviewed-by: Hannes Payer <hpayer@chromium.org> Reviewed-by: Dan Elphick <delphick@chromium.org> Cr-Commit-Position: refs/heads/master@{#75155}

[bazel] Fix build with GCC and older versions of Clang. Clang 12 doesn't support -Wno-bitwise-instead-of-logical, so silence it with -Wno-unknown-warning-option. GCC requires using GNU dialect of the C++ standard, using optimizations (otherwise "always_inline" fails to inline), and produces a lot of warnings that had to be silenced.
