This patch fixes test case failures on arm targets due to '-mstructure-size-boundary' being deprecated. The test cases were failing because a warning was being issued and due to the fact that the size of packed and unpacked structures is the same after deprecating '-mstructure-size-boundary'

Okay for trunk?

2017-08-04  Michael Collison  <michael.collison@arm.com>

	* testsuite/g++.dg/ext/packed8.C: Skip test for arm_eabi.

Why would we want to skip the test?  If you delete the
-mstructure-size-boundary option then the test should execute correctly
on all arm-eabi based platforms and most other ARM platforms where 8 was
the default anyway.

Because the comment (for example) in g+=.dg/ext/packed8.C says

 // NOTE: This test assumes packed structure layout differs from unpacked
//       structure layout.  This isn't true, e.g., with the default
//       arm-none-elf options.

If we could just delete the -mstructure-size-boundary=8 option why was it added in the first place?

Because the comment it out of date.  It was added at a time when the
default structure size boundard (pre eabi) was 32.

Patch updated to remove -mstructure-size-boundary from tests based on comments from Richard. Outdated comments also removed.

Okay for trunk?

2017-08-01  Michael Collison  <michael.collison@arm.com>

	* testsuite/g++.dg/ext/packed8.C: Remove -mstructure-size boundary
	option and fix comment.
	* testsuite/g++.dg/init/array16.C: Remove -mstructure-size boundary
	option and fix comment.
	* testsuite/g++.dg/other/crash-4.C: Remove -mstructure-size boundary
	option and fix comment.
	* testsuite/gcc.dg/builtin-stringop-chk-1.c: Remove
	-mstructure-size boundary option.
