Eric Pouech 82ea35cbb5 dbghelp/dwarf: Fix computation of some location attributes. 
Dwarf4 clarified that only FORM_sec_offset can refer to location
lists, fix dwarf2_compute_location_attr accordingly.

This fixes the 'fixme:dwarf2_parse_udt_member: Found register, while
not expecting it' messages.

Eric Pouech acfcd84a05 dbghelp/dwarf: Workaround functions with multiple range of addresses. 
gcc can emit functions with code spread across non contiguous code areas.
We used to register those functions with an address range enclosing all ranges
(meaning that all addresses not actually belonging to the function but
lying in that address range could be returned by dbghelp as belonging
to the function).

Work around this by registering the function with only the first range
of addresses (this will avoid the errors described above), but will
fail to mark the other address ranges as part of the function.

dbghelp doesn't seem to have explicit support of those cases, even if
pdb/codeview also support functions with multi range of addresses
(see S_SEPCODE).

Eric Pouech 0c3274b526 dbghelp/msc: Better detect whether IPI stream is present. 
Old version of PDB files can have a stream #4 which is not an IPI stream
Available documentation isn't 100% clear about when IPI has been
introduced.
So decide that IPI is present when header of stream looks like a type
stream header.
