Log:
use __builtin_alloca, drop non-standard alloca.h

Since alloca.h is not ISO C, most of our alloca-using tests seem to
rely on __builtin_alloca instead of including the header and calling
alloca.  This patch extends this practice to some of the exceptions I
found in gcc.target, marking them as requiring a functional alloca
while at that.

	* gcc.target/arc/interrupt-6.c: Use __builtin_alloca, require
	effective target support for alloca, drop include of alloca.h.
