Enum type for float denormalization style

Enumerated type with possible denormalization property for floating types. It is the type of member denorm_style in the numeric_limits class template.

Denormalization is the ability of a type to use a variable number of bits as exponent.

It is defined as:

1 2 3 4 5

enum float_denorm_style {
  denorm_indeterminate  = -1,
  denorm_absent         = 0,
  denorm_present        = 1
};

With the following possible values:

label	value	meaning
`denorm_intermediate`	`-1`	Denormalization style for the type cannot be determined at compile time
`denorm_absent`	`0`	The type does not allow denormalized values
`denorm_present`	`1`	The type allows denormalized values

The default value in the non-specialized numeric_limits class for its denorm_style member is denorm_absent (0).
