[patch, testsuite, PR80606] Remove default_packed lines from i386/avx-vtestp{d,s}*

[Tom de Vries]

Hi,

The test-cases i386/avx-vtestp{d,s}* contain lines guarded with target 
default_packed, using absolute line numbers 150 and 164.  The absolute 
line numbers intend to refer to the position of the packed attribute in 
unions ieee754_float and ieee754_double in m128-check.h, but they do not 
match the actual lines.

The default_packed lines were introduced for netware support in 2009, 
but netware support was removed in 2011.

The line numbers changes from:
...
    149	      unsigned sign : 1;
    150	   } bits __attribute__((packed));
    151	};
--
    163	      unsigned sign : 1;
    164	   } bits __attribute__((packed));
    165	};
...

to:
...
    149	      unsigned long frac : 23;
    150	      unsigned exp : 8;
    151	      unsigned sign : 1;
--
    163	      unsigned long frac0 : 20;
    164	      unsigned exp : 11;
    165	      unsigned sign : 1;
...
in Jan 2014 in r207150.

Apparently nobody noticed when the line numbers changed, so they are 
effectively unmaintained.

This patch removes the unmaintained lines.

Tested on x86_64.

OK for trunk?

Thanks,
- Tom
