[PATCH 5/8] gdb/xcoffread: allocate symbol table using vector in scan_xcoff_symtab

[Simon Marchi <simon.marchi@efficios.com>]

The symbol table content is only needed for the duration of
scan_xcoff_symtab, so it's not necessary to allocate it on the objfile
obstack.  Switch to using a vector that is freed at the end of the
function.
