Craig Topper f58341c6ee [TableGen] Fix line wrapping logic for the autogenerated header to use math that makes more sense (at least to me). 
The old code had a bug if the description was between 75 and 85 characters or so as it substracted PSLen from Desc.size() instead of MAX_LINE_LEN in the compare. It also calculated odd values for PosE on the last split and just let StringRef::slice take care of it being larger than the description string.

Craig Topper 33684f9e64 [TableGen] Rewrite an assert to not do a bunch unsigned math and then try to ensure the result is a positive number. 
I think the fact that it was explicitly excluding 0 kept this from being a tautology. The exclusion of 0 for the old math was also a bug that's easily hit if the description gets split into multiple lines.

Nadav Rotem f0705254d1 A bugfix for tblgen, in the function ‘emitSourceFileHeader’. 
When the first parameter (‘Desc’) is more than 80 characters long, it will result the header line that contains the description to be more
Than (4GB!) long. Not only it takes forever to produce, the output file cannot be open, since its ginormous.

Benjamin Kramer 83aa94711b Emit TableGen's header comment with C-style comments, so it can be used from C89 code. 
Should silence warnings when compiling the X86 disassembler.

Jakob Stoklund Olesen 1c66b87f7d Eliminate struct TableGenBackend. 
TableGen backends are simply written as functions now.

Jakob Stoklund Olesen e6aed139f0 Write llvm-tblgen backends as functions instead of sub-classes. 
The TableGenBackend base class doesn't do much, and will be removed
completely soon.
