Detailed Description
TargetLibraryInfo - This immutable pass captures information about what library functions are available for the current target, and allows a frontend to disable optimizations through -fno-builtin etc.

disableAllFunctions - This disables all builtins, which is used for options like -fno-builtin.

| LibFunc::Func & | F | ||
| ) | const |
getLibFunc - Search for a particular function name. If it is one of the known library functions, return true and set F to the corresponding value.
