d089e1f0 - [llvm] Change the implementation of isValidFeatureListFormat (#219266)

[llvm] Change the implementation of isValidFeatureListFormat (#219266) This is mostly to change the function-local static variable because some programs are having static initialization order problems. Also the coding standard states statics with ctor/dtor should be avoided. The new implementation also does not use Regex anymore.
