DWARFASTParserClang: Move attribute parsing into a single function
Summary:
The ParseTypeFromDWARF function consists of a huge switch on the kind of
type being parsed. Each case in this switch starts with parsing the
attributes of the current DIE. A lot of these attributes are specific to
one kind of a type, but a lot of them are common too, leading to code
duplication.
This patch reduces the duplication (and the size of ParseTypeFromDWARF)
by moving the attribute parsing to a separate function. It creates a
struct (ParsedTypeAttributes), which contains a parsed form of all
attributes which are useful for parsing any kind of a type. The parsing
code for a specific type kind can then access the fields which are
relevant for that specific case.
