Hello!
Attached patch enables sync_long_long tests on 32bit x86 and alpha.
Enabling the tests for alpha is obvious (it is 64bit-by-default
target, after all), but 32bit x86 needs at least -march=pentium passed
via dg-options. My previous patch checks bit_CMPXCHG8B cpuid bit
before compiling these

Adding -msse to failing test works OK.
