Log:
Provide synthetic children for some vector types
Unlike GDB, we tackle the problem of representing vector types in different styles by having a synthetic child provider that recognizes the format you're trying to apply to the variable, and coming up with the right type and number of child values to match that format
This makes for a more compact representation and less visual noise
Fixes rdar://5429347
