[Ada] Crash processing Valid_Scalars whose evaluation is always true
The compiler blows up generating code associated with occurrences of attribute
Valid_Scalars whose evaluation is always true. After this patch the following
test compiles fine.
2018-05-23 Javier Miranda <miranda@adacore.com>
gcc/ada/
* sem_attr.adb (Valid_Scalars): Do not invoke Error_Attr_P to report
the warning on occurrences of this attribute whose evaluation is always
true (since that subprogram aborts processing the attribute). In
addition, replace the node by its boolean result 'True' (required
because the backend has no knowledge of this attribute).
gcc/testsuite/
* gnat.dg/valid_scalars1.adb: New testcase.
