Fix rtx_code_size static initialization order fiasco
r264556 and r264537 changed the format of EQ_ATTR_ALT RTXs to "ww",
which also required adjusting rtx_code_size initializer. In order to
simplify things, the list of rtx_codes known to use HOST_WIDE_INTs was
replaced by the format string check. However, unlike the old one, this
new check cannot be always performed at compile time, in which case a
static constructor is generated. This may lead to a static
initialization order fiasco with respect to other static constructors
in the compiler, in case of PR87747, cselib's pool_allocator.
