to rename identifiers to meet the project (not LLVM) coding standard.

11225c978b [flang] Remove unnecessary unique_ptr. 
The unique_ptr around the vector of char was unnecessary. We can just
move the vector itself and it still keeps the same stream of chars.

6f4f772685 [flang] Change how cooked source is saved 
Rather than save the entire CookedSource object in the module scope,
all we need is the vector of characters that CharBlock has references
into. This avoids the problem that CookedSource object has a dangling
reference to an AllSources object (which shouldn't be needed by the
CharBlocks in the symbol table, but is there).

This also decouples Scope from parser classes other than CharBlock.

9e48304374 [flang] Refactor ModFileReader to use parser::Parsing 
parser::Parsing does most of the work needed to prescan and parse a file.
The only problem is that for module files we need to take ownership of
the cooked character stream so that it lives as long as the module scope
does.

To achieve this, change Parsing::cooked_ to be a unique_ptr and add a
member function to allow the caller to take ownership of it.
