Test for solaris cc bug with bit-fields.
With "cc -fast" (or, rather, "cc -xalias_level=basic -xO3", implied by
"cc -fast") solaris cc compiles incorrect code for bit-field accesses,
notably not rechecking data after functions calls in some situations.
Using "-xalias_level=any" resolves the problem (as well as using any
non-bit-field type).
Tested cc version is "Sun C 5.9 SunOS_i386 2007/05/03" (Sun Studio 12).
