[Patch, testsuite] Make some more tests xfail/pass/unsupported for avr

[Senthil Kumar Selvaraj <senthil_kumar dot selvaraj at atmel dot com>]

Hi,

 This patch attempts to fix some bogus testsuite failures by either
 slightly modifying the test, adding xfail for int16 targets, or by
 using the appropriate dg-require-effective-target/dg-skip-if directive.

 The only tricky changes I see are

 * changing usage of unsigned long to __SIZE_TYPE__ aka size_t for a
 couple of tests (arg type of malloc in Warray-bounds-11.c
 and in a typedef for size_t in pr62090-2.c). This makes the tests pass
 for avr and x86_64.

 * Skipping pr70169.c for avr, as the test doesn't appear valid for a
 modified Harvard architecture. The compiler warns that the pointer is
 attempting to access data memory with a program memory address, and the
 extra warning causes the test to fail.

 Regtesting with x86_64 showed no new regressions. The avr target of course
 shows a bunch of new PASS/UNSUPPORTED/XFAILs.

 If ok, could someone commit please? I don't have commit access.

Regards
Senthil
