    testsuite: i386: Require dfp support in gcc.target/i386/pr117946.c etc.
    
    Two tests FAIL on 64-bit Solaris/x86:
    
    FAIL: gcc.target/i386/pr117946.c (test for excess errors)
    FAIL: gcc.target/i386/pr118017.c (test for excess errors)
    
    The failure mode is the same in both cases:
    
    Excess errors:
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.target/i386/pr117946.c:4:47: 
error: decimal floating-point not supported for this target
    
    Excess errors:
    /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.target/i386/pr118017.c:6:47: 
error: decimal floating-point not supported for this target
    
    Fixed by requiring dfp support.
    
    Tested on i386-pc-solaris2.11 and x86_64-pc-linux-gnu.

            gcc/testsuite:
            * gcc.target/i386/pr117946.c: Require dfp support.
            * gcc.target/i386/pr118017.c: Likewise.  Use
            dg-require-effective-target for both this and int128.
