  1. Fix issue 20019: Symbol not found: _dyld_enumerate_tlv_storage on mac… 

    …OS 10.15

Ported from 378fc6d

The symbol `dyld_enumerate_tlv_storage` has been used to iterate all
the thread local storage addresses and registered them as roots with
the garbage collector.

The symbol has always been a private symbol, not part of the public
API. In the latest version of macOS, 10.15 it has been removed.

This replaces the usage of `dyld_enumerate_tlv_storage` by manually
iterating the TLV sections of all images and get key that the dynamic
loader has setup for each TLS symbol. The key is then used to get the
base address of the TLV storage.
