analyzer: don't assume target has alloca [PR102779]
gcc/testsuite/ChangeLog: PR analyzer/102779 * gcc.dg/analyzer/capacity-1.c: Add dg-require-effective-target alloca. Use __builtin_alloca rather than alloca. * gcc.dg/analyzer/capacity-3.c: Likewise. Signed-off-by: David Malcolm <dmalcolm@redhat.com>
