Minor cleanup.  But all the runtime feature stuff into RUNTIME.

Initial support for SSE2.  This compiles itself ok on Linux, and
should work on OSX.  Much cleanup is needed, and still need to restore
buildability without SSE2.

Use bootfiles/19e/boot-2008-09-sse2.lisp as the cross-compile script.

The key changes are in these new files:

o float-sse2.lisp: implements all of the floating-point stuff with
o sse2-array.lisp: replacement vops using sse2 instead of x87
o sse2-c-call.lisp: replacement vops using sse2 instead of x87.
o sse2-sap.lisp: replacement vops using sse2 instead of x87

o Basically turn off all the special routines that use the x87 trig,
  log, or exp instructions.  We don't support that currently.  (Would
  be nice, though.)
o Turn on %%sin and friends, like on ppc.
o Turn off %sin-quick and friends since we don't want to use x87 now.

o Register :sse2 feature.

o Disable transforms for x86 that use x87 instructions.  We don't
  support that with sse2.

o Load up the appropriate sse2 files for the compiler.  This will
  currently overwrite existing vops with vops for SSE2.

o Disable various vops using the x87 instructions, since
  float-sse2.lisp doesn't have equivalents.  (Just in case.  Since
  this isn't compiled or loaded, we shouldn't need to do this.)

o Add support for SSE2 instructions.  Shamelessly borrowed from our
  SBCL friends.

o Turn off some fp-constants that are not supported with sse2.
o Print FP registers as XMM instead of FR.

o Enable FEATURE_SSE2 flag when compiling.

o Get the mxcsr status bits too when getting the FPU status from a

o For SSE2, we copy any floating-point result (in ST(0)) to XMM0, so
  Lisp code can get it.

o Compile up the SSE2 files as needed.
