Record member functions in CodeView struct definitions

CodeView has two ways of recording struct member functions.
Non-overloaded functions have an LF_ONEMETHOD sub-type in the field
list, which records the name and the function type (LF_MFUNCTION).
Overloaded functions have an LF_METHOD instead, which points to an
LF_METHODLIST, which is an array of links to various LF_MFUNCTION types.
