Add Position-independent Code model Module API. Summary: This makes PIC levels a Module flag attribute, which can be queried by the backend. The flag is named `PIC Level`, and can have a value of: 0 - Backend-default 1 - Small-model (-fpic) 2 - Large-model (-fPIC) These match the `-pic-level' command line argument for clang, and the value of the preprocessor macro `__PIC__'. Test Plan: New flags tests specific for the 'PIC Level' module flag. Tests to be added as part of a future commit for PowerPC, which will use this new API.

[IR] AutoUpgrade ModuleFlagBehavior for PIC and PIE level Summary: From r303590, ModuleFlagBehavior for PIC and PIE level is changed from Error to Max. This will cause bitcode compatibility issue when linking against a bitcode static archive built with old compiler. Add an auto-ugprade path to upgrade the the ModuleFlagBehavior in the old bitcode to match the new one so IRLinker can link them.
