[1/77] Add an E_ prefix to mode names
Later patches will add wrapper types for specific classes
of mode. E.g. SImode will be a scalar_int_mode, SFmode will be a
scalar_float_mode, etc. This patch prepares for that change by adding
an E_ prefix to the mode enum values. It also adds #defines that map
the unprefixed names to the prefixed names; e.g:
#define QImode E_QImode
Later patches will change this to use things like scalar_int_mode
where appropriate.
The patch continues to use enum values to initialise static data.
This isn't necessary for correctness, but it cuts down on the amount
of load-time initialisation and shouldn't have any downsides.
The patch also changes things like:
cmp_mode == DImode ? DFmode : DImode
to:
cmp_mode == DImode ? E_DFmode : E_DImode
This is because DImode and DFmode will eventually be different
classes, so the original ?: wouldn't be well-formed.

C: fix logic within c_expr::get_location
In r251239 I added a c_expr::get_location method for use by
c_parser_expr_list for building the vec<location_t> for
an expression list, rather than using the location of the first token.
When determining whether to use the location within the tree node,
or fall back to the range in the c_expr, I used EXPR_CAN_HAVE_LOCATION,
rather than EXPR_HAS_LOCATION. This meant that any tree nodes of kinds
that *can* have a location but which erroneously had
EXPR_LOCATION (value) == UNKNOWN_LOCATION
had that value added to the vec<location_t>, leading to missing
location information when reporting on the issue
(seen with gcc.dg/Wtraditional-conversion-2.c for m68k).
This patch addresses this in two ways:
(a) it fixes the specific issue in this failing test case, by
setting up the location properly on the EXCESS_PRECISION_EXPR.
(b) updating c_expr::get_location by only using the EXPR_LOCATION
if it's sane. Arguably this is papering over bugs, but they are
pre-existing ones exposed by r251239, and I'd rather have this
fix in place than play whack-a-mole on any other such "missing
location" bugs that are lurking in the codebase.
gcc/c/ChangeLog:
* c-tree.h (c_expr::get_location) Use EXPR_HAS_LOCATION rather
than CAN_HAVE_LOCATION_P when determining whether to use the
location_t value within "value".
gcc/c-family/ChangeLog:
* c-lex.c (interpret_float): Use token location
when building an EXCESS_PRECISION_EXPR.
