Simplify llvm::cl::Option by using a bit field instead of manual bit packing.
This still preserves the same total layout.
Previously it looked like:
*** Dumping AST Record Layout
0 | class llvm::cl::Option
0 | (Option vtable pointer)
8 | int NumOccurrences
12 | int Flags
16 | unsigned int Position
20 | unsigned int AdditionalVals
24 | class llvm::cl::Option * NextRegistered
32 | const char * ArgStr
40 | const char * HelpStr
48 | const char * ValueStr
sizeof=56, dsize=56, align=8
nvsize=56, nvalign=8
Now it looks like:
*** Dumping AST Record Layout
0 | class llvm::cl::Option
0 | (Option vtable pointer)
8 | int NumOccurrences
12 | enum NumOccurrencesFlag Occurrences
12 | unsigned int Value
12 | enum OptionHidden HiddenFlag
12 | enum FormattingFlags Formatting
13 | unsigned int Misc
16 | unsigned int Position
20 | unsigned int AdditionalVals
24 | class llvm::cl::Option * NextRegistered
32 | const char * ArgStr
40 | const char * HelpStr
48 | const char * ValueStr
sizeof=56, dsize=56, align=8
nvsize=56, nvalign=8
