testsuite: new require effective target indirect_calls

Browse Source 
This patch adds a new dg_require_effective_target procedure to the
testsuite infrastructure: indirect_calls.  This new function tells
whether a target supports calls to non-constant call targets.
    
This patch also annotates the tests in the gcc.c-torture testuite that
require support for indirect calls.
    
    gcc/ChangeLog:
    
            * doc/sourcebuild.texi (Effective-Target Keywords): Document
            indirect_calls.
    
    gcc/testsuite/ChangeLog:
    
            * lib/target-supports.exp (check_effective_target_indirect_calls):
            New proc.
