testsuite: i386: Fix gcc.target/i386/pieces-memcpy-7.c etc. on Solaris/x86

gcc.target/i386/pieces-memcpy-7.c etc. FAIL on 32-bit Solaris/x86:

FAIL: gcc.target/i386/pieces-memcpy-7.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memcpy-8.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memcpy-9.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-36.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-40.c scan-assembler-not %[re]bp
FAIL: gcc.target/i386/pieces-memset-9.c scan-assembler-not %[re]bp

The problem is that the tests assume -mno-stackrealign while 32-bit
Solaris/x86 defaults to -mstackrealign.

Fixed by explicitly specifying -mno-stackrealign.

Tested on i386-pc-solaris2.11 and i686-pc-linux-gnu.

	gcc/testsuite:
	* gcc.target/i386/pieces-memcpy-7.c (dg-additional-options): Add
	-mno-stackrealign.
	* gcc.target/i386/pieces-memcpy-8.c: Likewise.
	* gcc.target/i386/pieces-memcpy-9.c: Likewise.
	* gcc.target/i386/pieces-memset-36.c: Likewise.
	* gcc.target/i386/pieces-memset-40.c: Likewise.
	* gcc.target/i386/pieces-memset-9.c: Likewise.
