  Log Message:
  -----------
  [NFC][AssemblyWriter] Allow AssemblyWriter::printBasicBlock() to print blocks that don't have parents.

Remove the assert in AssemblyWriter::printBasicBlock() and
in BasicBlock::isEntryBlock() that require blocks to have parents.
Instead, have BasicBlock::isEntryBlock() return false for unattached
blocks. This allows us to call these functions for blocks that are
not yet added to a module which is a useful debugging capability.
