Zachary Turner 23df1319ca [MS Demangler] Properly handle function parameter back-refs. 
Properly demangle function parameter back-references.

Previously we treated lists of function parameters and template
parameters the same. There are some important differences with regards
to back-references, and some less important differences regarding which
characters can appear before or after the name.

The important differences are that with a given type T, all instances of
a function parameter list share the same global back-ref table.
Specifically, if X and Y are function pointers, then there are 3
entities in the declaration X func(Y) which all affect and are affected
by the master parameter back-ref table:
  1) The parameter list of X's function type
  2) the parameter list of func itself
  3) The parameter list of Y's function type.

The previous code would create a back-reference table that was local to
a single parameter list, so it would not be shared across parameter
lists.

This was discovered when porting ms-back-references.test from clang's
mangling tests. All of these tests should now pass with the new changes.

In doing so, I split the function for parsing template and function
parameters into two separate functions. This makes the template
parameter list parsing code in particular very small and easy to
understand now.
