PR c++/83799 reports a failure building LLVM due to a bogus
"no matching function for call to" error at a callsite like this:
  TLI->getTypeLegalizationCost(DL);
where "DL" is from:
  using TargetTransformInfoImplBase::DL;

The root cause is that type_dependent_expression_p on a USING_DECL
should return true when processing a template, but after r256448 the
the argument at the callsite is a location wrapper around the USING_DECL,
and type_dependent_expression_p erroneously returns false for it, as
it is comparing tree codes, and failing a match, then looking at types.

This prevents cp_parser_postfix_expression from using the
"build_min_nt_call_vec" path for handling the call, instead erroneously
handling it via build_new_method_call (which fails for this case).

This patch fixes the problem by stripping any location wrappers before
the various tree code tests in type_dependent_expression_p.   It fixes
the reduced test case, and the full BasicTargetTransformInfo.ii; after
this patch, the assembly generated for that latter case is identical to
that generated before r256448.

This is an awkward testsuite failure. The original bug was that we were failing to put out
the conditional code in the conditional form of the STL instruction (oops!).
So we wanted to output STLNE, but instead output STL.
The testacase relies on if-conversion to conditionalise the insn for STL.
However, ever since r251643 the expansion of a non-relaxed atomic store
always includes a compiler barrier. That blocks if-conversion in all cases.

So there's no easy way to get to a conditional STL instruction from a C program.
But we do want to test for the original bug fix that if the RTL insn for STL is conditionalised
it should output the conditional code.

The solution in this patch is to convert the test into an RTL test with the COND_EXEC form
of the STL insn and scan the assembly output there.
This seems to work fine, and gives us an opportunity to create a gcc.dg/rtl/arm directory
in the RTL tests.

This now makes the gcc.target/arm/stl-cond.c disappear (as the test is deleted) and
the new test in gcc.dg/rtl/arm/stl-cond.c passes.

This patch converts gcc.target/arm/pr40887.c to use the proper effective target check and dg-add-options for armv5te
so that we avoid situations where we end up trying to compile the test with a Thumb1 hard-float ABI, which makes the
compiler complain.

This allows the test to pass gracefully for me for my compiler configured with:
--with-cpu=cortex-a15 --with-fpu=neon-vfpv4 --with-float=hard --with-mode=thumb

This test is naughty because it doesn't use the proper effective target checks

This PR is about a case in which we VIEW_CONVERT a variable-sized
unaligned record:

 <record_type 0x7ffff6d92888 check_displace_generation__T245b sizes-gimplified type_7 BLK
    size <var_decl 0x7ffff6846510 D.3499 ...>
    unit-size <var_decl 0x7ffff68465a0 D.3500 ...>
    align:8 ...>

to an aligned 32-bit integer.  The strict-alignment handling of
this case creates an aligned temporary slot, moves the operand
into the slot in the operand's original mode, then accesses the
slot in the more-aligned result mode.

Previously the size of the temporary slot was calculated using:

                  HOST_WIDE_INT temp_size
                    = MAX (int_size_in_bytes (inner_type),
                           (HOST_WIDE_INT) GET_MODE_SIZE (mode));

int_size_in_bytes would return -1 for the variable-length type,
so we'd use the size of the result mode for the slot.  r256152 replaced
int_size_in_bytes with tree_to_poly_uint64, which triggered an ICE.

If op0 has BLKmode we do a block copy of GET_MODE_SIZE (mode) bytes
and then convert the slot to "mode":

                  poly_uint64 mode_size = GET_MODE_SIZE (mode);
                  ...
                  if (GET_MODE (op0) == BLKmode)
                    {
                      rtx size_rtx = gen_int_mode (mode_size, Pmode);
                      emit_block_move (new_with_op0_mode, op0, size_rtx,
                                       (modifier == EXPAND_STACK_PARM
                                        ? BLOCK_OP_CALL_PARM
                                        : BLOCK_OP_NORMAL));
                    }
                  else
                    ...

                  op0 = new_rtx;
                }
            }

          op0 = adjust_address (op0, mode, 0);

so I think in that case just the size of "mode" is enough, even if op0
is a fixed-size type.  For non-BLKmode op0 we first move in op0's mode
and then convert the slot to "mode":

                    emit_move_insn (new_with_op0_mode, op0);

                  op0 = new_rtx;
                }
            }

          op0 = adjust_address (op0, mode, 0);

so I think we want the maximum of the two mode sizes in that case.

vect_analyze_loop_operations was calling vectorizable_live_operation
for all live-out phis, which led to a bogus ncopies calculation in
the pure SLP case.  I think v_a_l_o should only be passing phis
that are vectorised using normal loop vectorisation, since
vect_slp_analyze_node_operations handles the SLP side (and knows
the correct slp_index and slp_node arguments to pass in, via
vect_analyze_stmt).

With that fixed we hit an older bug that vectorizable_live_operation
didn't handle live-out SLP inductions.  Fixed by using gimple_phi_result
rather than gimple_get_lhs for phis.
