COFFObjectFile ignore broken symbol table

[Bandzi Michal via llvm-commits]

Hello,

When binaries are compressed by UPX, information about symbol table  
offset and symbol count remain unchanged (but became invalid due to  
compression). This causes failure in constructor and rest of the  
binary cannot be processed.

In proposed patch (attachment), when symbol table initialization  
fails, constructor does not return error, but rather resets symbol  
related information (symbol/string table pointers, sizes) - this  
should disable related iterators and function while rest of the binary  
can be processed.
