  Changed paths:
    M llvm/include/llvm/ExecutionEngine/JITSymbol.h

  Log Message:
  -----------
  [ExecutionEngine] Add a jitTargetAddressToFunction utility function.

jitTargetAddressToFunction takes a JITTargetAddress and returns a pointer of
the given function pointer type suitable for calling to invoke the function
at the target address.

jitTargetAddressToFunction currently behaves the same as
jitTargetAddressToPointer, but in the near future will be updated to perform
pointer signing on architectures that require it (e.g. arm64e). For this
reason it should always be preferred when generating callable pointers for
JIT'd functions.

  Log Message:
  -----------
  [ORC] Add a runAsMain utility function to ExecutionUtils.

The runAsMain function takes a pointer to a function with a standard C main
signature, int(*)(int, char*[]), and invokes it using the given arguments and
program name. The arguments are copied into writable temporary storage as
required by the C and C++ specifications, so runAsMain safe to use when calling
main functions that modify their arguments in-place.

This patch also uses the new runAsMain function to replace hand-rolled versions
in lli, llvm-jitlink, and the SpeculativeJIT example.
