* gdbarch.sh (CONVERT_REGISTER_P): Add "type" parameter.
(REGISTER_TO_VALUE, VALUE_TO_REGISTER): Replace raw buffer
parameter with "frame".
* gdbarch.h, gdbarch.c: Re-generate.
* frame.h (put_frame_register): Declare.
* frame.c (put_frame_register): New function.
* arch-utils.c (legacy_convert_register_p): Add "type" parameter.
(legacy_register_to_value): Rewrite, use "frame" to get the
register value.
(legacy_value_to_register): Rewrite, use "frame" to find the
register's location before storing.
* arch-utils.h (legacy_convert_register_p): Update.
(legacy_register_to_value, legacy_value_to_register): Update.
* findvar.c (value_from_register): Rewrite, eliminate use of
REGISTER_CONVERT_TO_TYPE, pass "type" to CONVERT_REGISTER_P, pass
"frame" to REGISTER_TO_VALUE.
* valops.c (value_assign): Move the CONVERT_REGISTER code to the
lval_reg_frame_relative + lval_register branch of the switch. Do
not use REGISTER_CONVERT_FROM_TYPE. Use put_frame_register.
* i386-tdep.c (I386_EBX_REGNUM, I386_ECX_REGNUM, I386_ESI_REGNUM,
I386_EDI_REGNUM): New defines.
(i386_next_regnum, i386_convert_register_p,
i386_register_to_value, i386_value_to_register): New functions.
(i386_register_convertible, i386_register_convert_to_virtual,
i386_convert_to_raw): Remove functions.
(i386_gdbarch_init): Set convert_register_p, register_to_value and
value_to_register instead of register_convertible,
register_convert_to_virtual and register_convert_to_raw.
* mips-tdep.c (mips_convert_register_p): New function.
(mips_value_to_register): Replace mips_register_convert_from_type.
(mips_register_to_value): Replace mips_register_convert_to_type.
(mips_gdbarch_init): Set conver_register_p, value_to_register and
register_to_value.
* alpha-tdep.c (alpha_convert_register_p): Update.
(alpha_value_to_register): Update, store the register.
(alpha_register_to_value): Update, fetch the register.
