SH3-E support from Allan Tajii <atajii@hmsi.com>:

* sh-tdep.c (sh_reg_names, sh3_reg_names): Add empty names for float registers. (sh3e_reg_names): New register name array. (sh_processor_type_table): Add sh3e processor type. * config/sh/tm-sh.h (REGISTER_VIRTUAL_TYPE): Fix test. (REGISTER_NAMES, NUM_REGS, NUM_REALREGS, etc): Adjust for full set of registers. * remote-e7000.c (want_sh3, want_sh3_nopc): New globals. (e7000_fetch_registers, e7000_wait): Use them. * sh3-rom.c (sh3_regnames): Add float registers. (sh3e_cmds, sh3e_ops): New globals. (sh3e_open): New function. (_initialize_sh3_rom): Rename from _initialize_sh3, set up sh3e target vector. * gdbwin.c (reg_order) [TARGET_SH]: Update for SH3-E. * initfake.c: Call _initialize_sh3_rom instead of _initialize_sh3.
