Rename temporary symbols if they conflict with artificial symbols created by the assembler. This was blocking parsing any large .s produced by clang for example. Fixes PR8596. llvm-svn: 120603

Don't store Twine temporaries, it's not safe. And don't append the name over and over again in the loop. llvm-svn: 129210

Centralize the handling of unique ids for temporary labels. Before this patch code wanting to create temporary labels for a given entity (function, cu, exception range, etc) had to keep its own counter to have stable symbol names. createTempSymbol would still add a suffix to make sure a new symbol was always returned, but it kept a single counter. Because of that, if we were to use just createTempSymbol("cu_begin"), the label could change from cu_begin42 to cu_begin43 because some other code started using temporary labels. Simplify this by just keeping one counter per prefix and removing the various specialized counters. llvm-svn: 232535
