[COMMITED] ada: Remove duplicated doc comment section

["Marc Poulhiès" <poulhies@adacore.com>]

From: Ronan Desplanques <desplanques@adacore.com>

A documentation section was duplicated by mistake in r0-110752.
This commit removes the copy that was added by r0-110752, but
integrates the small editorial change that it brought to the
original.

gcc/ada/

	* einfo.ads: remove documentation duplicate

Tested on x86_64-pc-linux-gnu, committed on master.

--- Delayed Freezing and Elaboration --

-
---  The flag Has_Delayed_Freeze indicates that an entity carries an explicit
---  freeze node, which appears later in the expanded tree.
-
---  a) The flag is used by the front-end to trigger expansion actions
---  which include the generation of that freeze node. Typically this happens at
---  the end of the current compilation unit, or before the first subprogram
---  body is encountered in the current unit. See files freeze and exp_ch13 for
---  details on the actions triggered by a freeze node, which include the
---  construction of initialization procedures and dispatch tables.

---  b) The flag is used by the backend to defer elaboration of the entity until
---  its freeze node is seen. In the absence of an explicit freeze node, an
---  entity is frozen (and elaborated) at the point of declaration.
-
---  For object declarations, the flag is set when an address clause for the
---  object is encountered. Legality checks on the address expression only
---  take place at the freeze point of the object.
-
---  Most types have an explicit freeze node, because they cannot be elaborated
---  until all representation and operational items that apply to them have been
---  analyzed. Private types and incomplete types have the flag set as well, as
---  do task and protected types.
-
---  Implicit base types created for type derivations, as well as classwide
---  types created for all tagged types, have the flag set.
-
---  If a subprogram has an access parameter whose designated type is incomplete
---  the subprogram has the flag set.
