Support for 64-bit location_t: RTL parts
Some RTL objects need to store a location_t. Currently, they store it in the
rt_int field of union rtunion, but in a world where location_t could be
64-bit, they need to store it in a larger variable. Unfortunately, rtunion
does not currently have a 64-bit int type for that purpose, so add one. In
order to avoid increasing any overhead when 64-bit locations are not in use,
the new field is dedicated for location_t storage only and has type
"location_t" so it will only be 64-bit if necessary. This necessitates
adding a new RTX format code 'L' for locations. There are very many switch
statements in the codebase that inspect the RTX format code. I took the
approach of finding all of them that handle code 'i' or 'n' and making sure
they handle 'L' too. I am sure that some of these call sites can never see
an 'L' code, but I thought it would be safer and more future-proof to handle
as many as possible, given it's just a line or two to add in most cases.
gcc/ChangeLog:

fields.

(gen_rtx_ASM_INPUT): Adjust to use sL format instead of si.
(gen_rtx_INSN): Adjust prototype to use location_r rather than int

local variable from int to location_t.
