Simon Marchi 76eb8ef1ce gdb: include gdbarch.h in all files extending gdbarch_tdep 
Commit 345bd07cce ("gdb: fix gdbarch_tdep ODR violation") made a bunch
of files define a *_gdbarch_tdep class that inherits from a gdbarch_tdep
base.  But some of these files don't include gdbarch.h, where
gdbarch_tdep is defined.  This may cause build errors if gdbarch.h isn't
already included by chance by some other header file.  Avoid this by
making them include gdbarch.h.
