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.
