["Iyer, Balaji V" <balaji dot v dot iyer at intel dot com>]

Hello Everyone,
	The attached patch will fix the issue reported in PR 59631. The main issue was the usage of Cilk spawn [and _Cilk_sync] with -fcilkplus caused an ICE. This patch should fix that. The issue was only reported for C++ but the issue exists in C compiler also.  This patch fixes both C and C++. A test case is also included.
 
Is this Ok for trunk?
