toolchain_utils: Add post-user flags to compiler_wrapper.

This adds the ability to add flags to the compiler command that
cannot be overridden by the user (e.g. when we MUST turn off a warning).
It adds '-Wno-implicit-int-float-conversion as such a flag for
llvm-next.

BUG=chromium:1018778
TEST='go test' passes
