Mark Vitale 22d841a45f SOLARIS: prevent BAD TRAP panic with Studio 12.5 
Starting with Solaris Studio 12.3, it is documented that Solaris kernel
modules (such as libafs) must not use any floating point, vector, or
SIMD/SSE instructions on x86 hardware.  However, each new Studio
compiler release (12.4 and especially 12.5) is more likely to use these
types of instructions by default.

If the libafs kernel module includes any forbidden kernel instructions,
Solaris will panic the system with:
  BAD TRAP:  type=7 (#nm Device not available)

Provide a new autoconfig test to specify the required compiler options
(-xvector=%none -xregs=no%float) when building the OpenAFS kernel module
for Solaris, so that no invalid x86 instructions are used.

In addition, reinstate default kernel module optimization for Solaris.
It had been disabled in commit 80592c53cb
to address this same issue in Studio 12.3 and 12.4.  However, Studio
12.5 started using some SSE instructions even with no optimization.

This commit has been tested with OpenAFS master and Studio 12.5 at all
optimization levels (none, -xO1 through -xO5) and verified to contain no
XMM register instructions via the following command:
  $ gobjdump -dlr libafs64.o | grep xmm | wc -l
