* rtl.def (SUBREG): Update comments.
* rtl.h (reg_attrs): Be explicit about the type of offset used.

(set_reg_attrs_from_value): ...this.
(adjust_reg_mode, byte_lowpart_offset): Declare.
* emit-rtl.c (byte_lowpart_offset): New function.
(update_reg_offset): Remove special offset handling for big-endian
targets.
(gen_rtx_REG_offset, gen_reg_rtx_offset): Explicitly say that the
offset parameter is added to REG_OFFSET.
(adjust_reg_mode): New function.
(set_reg_attrs_for_mem): Rename to...
(set_reg_attrs_for_value): ...this and generalize to all values.
If the register is a lowpart of the value, adjust the offset
accordingly.
(set_reg_attrs_for_parm): Update after the above renaming.
(set_reg_attrs_for_decl_rtl): New function, split out from
set_decl_incoming_rtl. Set the offset of plain REGs to the
offset of the REG's mode from the decl's. Assert that all
subregs are lowparts and handle their inner registers in the
same way as plain REGs.

is a SUBREG_BYTE.

(mode_for_reg_attrs): Replace with...
(track_loc_p): ...this new function. Return the mode and offset
to the caller, checking that the latter is valid. If the rtx is
a paradoxical lowpart of the decl, use the decl's mode instead.
Do the same when storing to a register that contains the entire decl.
(var_lowpart): Use byte_lowpart_offset rather than
subreg_lowpart_offset when adjusting the offset attribute.
(count_uses, add_uses, add_stores): Use track_reg_p instead of
REG_EXPR, MEM_EXPR, REG_OFFSET, INT_MEM_OFFSET, track_expr_p,
offset_valid_for_tracked_p and mode_for_reg_attrs. Generate
lowparts for MEMs as well as REGs.
(vt_add_function_parameters): When obtaining the information from
the decl_rtl, adjust the offset to match incoming. Use track_loc_p
and var_lowpart.
