Craig Topper da7cf8ab2b Move individual group name strings from the OptionTable into one big char array. Then only store offsets into it in the OptionTable. Saves about 4K from the clang binary and removes 400 relocation entries from DiagnosticIDs.o.

Craig Topper d80c17e060 Merge diagnostic group tables to reduce data size and relocation entries. 
The individual group and subgroups tables are now two large tables. The option table stores an index into these two tables instead of pointers. This reduces the size of the options tabe since it doesn't need to store pointers. It also reduces the number of relocations needed.

My build shows this reducing DiagnosticsIDs.o and the clang binary by ~20.5K. It also removes ~400 relocation entries from DiagnosticIDs.o.

Jordan Rose 2fe20dca2a [diagtool] Re-add show-enabled, minimizing the code pulled in from Frontend. 
Now correctly builds with both GNU make and CMake.

Jordan Rose 573649eb8b [diagtool] Pull show-enabled back out for now. 
Need to figure out how to get Frontend's warning parsing without bringing
in all of Frontend.

Jordan Rose d617e06997 [diagtool] Add 'show-enabled', which displays which warnings are enabled. 
show-enabled uses the command line you give it to build a CompilerInstance,
so any flags you pass will be processed as if running clang proper.
