Saleem Abdulrasool 3fa1d1fe3f runtime: ingest LLVMSupport into the runtime
This adds a new copy of LLVMSupport into the runtime.  This is the final
step before changing the inline namespace for the runtime support.  This
will allow us to avoid the ODR violations from the header definitions of
LLVMSupport.

LLVMSupport forked at: 22492eead218ec91d349c8c50439880fbeacf2b7
Changes made to LLVMSupport from that revision:
  process.inc forward declares `_beginthreadex` due to compilation issues due to custom flag handling

API changes required that we alter the `Deallocate` routine to account
for the alignment.

This is a temporary state, meant to simplify the process.  We do not use
the entire LLVMSupport library and there is no value in keeping the
entire library.  Subsequent commits will prune the library to the needs
for the runtime.
