Right now, gdbsupport/common-regcache.h contains two abstractons for a regcache. An opaque type `regcache` (gdb and gdbserver both have their own regcache that is the concrete version of this) and an abstract base class `reg_buffer_common`, that is the base of regcaches on both sides. These abstractions allow code to be written for both gdb and gdbserver, for instance in the gdb/arch sub-directory. However, having two different abstractions is impractical. If some common code has a regcache, and wants to use an operation defined on reg_buffer_common, it can't. It would be better to have just one. Change all instances of `regcache *` in gdbsupport/common-regcache.h to be `reg_buffer_common *`, then fix fallouts. Implementations in gdb and gdbserver now need to down-cast (using gdb::checked_static_cast) from reg_buffer_common to their concrete regcache type. Some of them could be avoided by changing free functions (like regcache_register_size) to be virtual methods on reg_buffer_common. I tried it, it seems to work, but I did not include it in this series to avoid adding unnecessary changes.
