    Original change's description:
    > [embedded] Share a single RelocInfo between all trampolines
    > 
    > Creates a single RelocInfo to be used by all builtin trampolines and
    > stores it as a root. All trampolines then substitute this for their
    > trampoline at generation time with DCHECKs to make sure it is
    > identical.
    > 
    > Also forces all non-trampoline RelocInfo ByteArrays for builtins to be
    > generated into RO_SPACE.
    > 
    > On x64, this results in the OLD_SPACE part of the startup snapshot
    > decreasing in size from 166096 to 131248 (-34848) bytes and RO_SPACE
    > (in the read-only snapshot) increasing from 31176 to 31248 (+72) bytes.
    > 
    > Bug: v8:8295
