[PATCH, testsuite]: Fix gcc.target/i386/pr65105-1.c test

[Uros Bizjak]

Hello!

Attached patch fixes gcc.target/i386/pr65105-1.c:

a) As a runtime SSE2 test, we have to check for target SSE2 support
and use proper test infrastructure.

b) A runtime test can't check output assembly without -save-temps.

The patch also use another misuse of -save-temps in gcc.target/i386 directory.

The patch solves:

UNRESOLVED: gcc.target/i386/pr65105-1.c scan-assembler por
UNRESOLVED: gcc.target/i386/pr65105-1.c scan-assembler pand

2015-10-01  Uros Bizjak  <ubiz...@gmail.com>

    * gcc.target/i386/pr65105-1.c: Require sse2 effective target.
    (main): Rename to sse2_test.  Abort if count != 5.
    (dg-options): Add -save-temps.  Use "-msse2 -mtune=slm" instead
    of -march=slm.
    * gcc.target/i386/pr46865-2.c (dg-options): Remove -save-temps.

Tested on x86_64-linux-gnu {,-m32} and committed to mainline SVN.

Uros.
