<pre>RuntimeDyld's symbol table doesn't currently distinguish between weak and
strong symbols. All symbols are currently treated as strong, leading to
spurious symbol clashes.
We should add a 'weak' flag to RuntimeDyld's symbol table. The symbol
visibility support introduced in r226341 provides a template for how to
approach this, but rather than add more methods (along the lines of
getExportedSymbolLoadAddress), we should change RuntimeDyld's getSymbolAddress
methods to return a RTDyldSymbol object that provides access to both the 'weak'
flag and visibility.</pre>
