Commit r210360 removed the first "i" field from the various instruction nodes in rtx.def, moving it to an explicit "int insn_uid;" field of the union "u2" within rtx_def. Update the comment in rtl.def to reflect this change. Also, fix a stray apostrophe. gcc/ChangeLog: * rtl.def: Update comment for "things in the instruction chain" to reflect the removal of the leading "i" field for INSN_UID in r210360.

128-bit SSE load and store instructions can be used for load and store of 128-bit integers if they are the only operations on 128-bit integers. To convert load and store of 128-bit integers to 128-bit SSE load and store, the original STV pass, which is designed to convert 64-bit integer operations to SSE2 operations in 32-bit mode, is extended to 64-bit mode in the following ways: 1. Class scalar_chain is turned into base class. The 32-bit specific member functions are moved to the new derived class, dimode_scalar_chain. The new derived class, timode_scalar_chain, is added to convert oad and store of 128-bit integers to 128-bit SSE load and store. 2. Add the 64-bit version of scalar_to_vector_candidate_p and remove_non_convertible_regs. Only TImode load and store are allowed for conversion. If one instruction on the chain of dependent instructions aren't TImode load or store, the chain of instructions won't be converted. 3. In 64-bit, we only convert from TImode to V1TImode, which have the same size. The difference is only vector registers are allowed in TImode so that 128-bit SSE load and store instructions will be used for load and store of 128-bit integers. 4. Put the 64-bit STV pass before the CSE pass so that instructions changed or generated by the STV pass can be CSEed. convert_scalars_to_vector calls free_dominance_info in 64-bit mode to work around ICE in fwprop pass: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70807 when building libgcc on Linux/x86-64. gcc/ PR target/70155 * config/i386/i386.c (scalar_to_vector_candidate_p): Renamed to ...

As discussed on <https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01708.html>, this change removes a field in the dw_loc_descr_node structure so we can get rid of the CHECKING_P macro usage. This field was used to perform consistency checks for frame offset in DWARF procedures. As a replacement, this commit turns the "visited nodes" set in resolve_args_picking_1 into a map that remembers for each dw_loc_descr_node the frame offset associated to it, so that the consistency check is still operational. Boostrapped and regtested on x86_64-linux. 2016-04-27 Pierre-Marie de Rodat <derodat@adacore.com> * dwarf2out.h (struct dw_loc_descr_node): Remove the dw_loc_frame_offset field. * dwarf2out.c (new_loc_descr): Likewise.
