Andrew Burgess ab25d9bbe4 gdb: rename gdbarch_tdep struct to fix g++ 4.8 build
After the commit:

  commit 08106042d9

      gdb: move the type cast into gdbarch_tdep

GDB would no longer build using g++ 4.8.  The issue appears to be some
confusion caused by GDB having 'struct gdbarch_tdep', but also a
templated function called 'gdbarch_tdep'.  Prior to the above commit
the gdbarch_tdep function was not templated, and this compiled just
fine.  Note that the above commit compiles just fine with later
versions of g++, so this issue was clearly fixed at some point, though
I've not tried to track down exactly when.

In this commit I propose to fix the g++ 4.8 build problem by renaming
'struct gdbarch_tdep' to 'struct gdbarch_tdep_base'.  This rename
better represents that the struct is only ever used as a base class,
and removes the overloading of the name, which allows GDB to build
with g++ 4.8.

I've also updated the comment on 'struct gdbarch_tdep_base' to fix a
typo, and the comment on the 'gdbarch_tdep' function, to mention that
in maintainer mode a run-time type check is performed.
