(cherry picked from v5-34-00-patches commit 0c5e70a2e44cb9f0370cb936ad84824645f92761)
Trailing whitespace cleanup.
Indentation.
Disable autoloading during meta operations. Likely fixes ROOT-6248.
Also replace boost::detail::atomic_exchange_and_add for the interpreter.

Generalize the __cxa_atexit replacement to cover more symbols.
Because the JIT cannot handle inline asm, provide compiled symbols for relevant
functions until cling has switched to MCJIT.
This fixes the use of many boost libraries (e.g. regex) in cling on x86_64/i386.
Kudos to Marco Clemencic for the idea!
Overriders for several new pure-virtual functions in TVirtualPad.
Fix non-GCC (and non-thread-safe!) case.
