This patch moves the calculation of costs for MEM into a
separate function, and reforms the calculation into two
parts. Firstly any additional cost of the addressing mode
is calculated, and then the cost of the memory access itself
is added.
In this patch, the calculation of the cost of the addressing
mode is omitted, to be added in a subsequent patch.

Early debug broke generation of .debug_rnglists when using both -gdwarf5
and -gsplit-dwarf. It introduces a generation for init_sections_and_labels,
but doesn't account for the generation of up to 4 unique ranges labels,
two created in init_sections_and_labels and two in output_rnglists.
Fix this by passing generation to output_rnglists and creating 4 unique
labels per generation.
Without this fix using -gdwarf-5 -gsplit-dwarf could result in:
Error: symbol `.Ldebug_ranges2' is already defined
gcc/ChangeLog:
* dwarf2out.c (init_sections_and_labels): Use generation to create
unique ranges_section_label and ranges_base_label. Return generation.
(output_rnglists): Add generation argument. Use generation to create
unique ranges labels.

and pass generation to output_rnglists.

jit.dg/test-error-array-bounds.c is a test of how libgccjit
handles errors coming from the middle-end, using -Warray-bounds as
an example.
It started failing as of r254830 (aka 987b3316c4e7c908e3c7d2151c20971f9707ad66),
due to that commit changing the wording of the message.
This commit fixes the jit testcase by updating it to use the new
wording.
