[Ada] Fix calls to Error_Msg_NE instead of Error_Msg_N

[Ada] Fix calls to Error_Msg_NE instead of Error_Msg_N

[Pierre-Marie de Rodat]

[-- Attachment #1: Type: text/plain, Size: 482 bytes --]

Replace calls to Error_Msg_NE whose Msg parameters have no insertion
characters corresponding to the E parameter with equivalent but simpler
calls to Error_Msg_N. Code cleanup; behaviour is unaffected.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* freeze.adb (Freeze_Profile): Replace Error_Msg_NE with
	Error_Msg_N; change to continuation message.
	* sem_cat.adb, sem_ch10.adb, sem_ch12.adb, sem_ch5.adb: Replace
	calls to Error_Msg_NE with calls to Error_Msg_N.
