Subject: [testsuite] Fix gcc.target/i386/hle-* testcases with Sun as

Several /gcc.target/i386/hle-*.c tests are currently failing on Solaris
9/x86 with Sun as:

FAIL: gcc.target/i386/hle-add-acq-1.c scan-assembler lock[ \\n\\t]+(xacquire|.byte[ \\t]+0xf2)[ \\t\\n]+add

The .s file has

        lock;
        .byte   0xf2

but the scan-assembler regex currently doesn't allow for the ; (which is
not present with gas 2.22).

The patch below does just that.  Tested with the appropriate runtest
invocation on i386-pc-solaris2.9 configured with as and gas
respectively.

Ok for mainline?
