d8c5b92f3f target/sparc: Split fcc out of env->fsr 
Represent each fcc field separately from the rest of fsr.
This vastly simplifies floating-point comparisons.

c9fa8e586b target/sparc: Remove cpu_fsr 
Drop this field as a tcg global, loading it explicitly in the
few places required.  This means that all FPop helpers may
once again be TCG_CALL_NO_WG.

These two fields are adjusted by all FPop insns.
Having them separate makes it easier to set without masking.

db71391123 target/sparc: Merge check_ieee_exceptions with FPop helpers 
If an exception is to be raised, the destination fp register
should be unmodified.  The current implementation is incorrect,
in that double results will be written back before calling
gen_helper_check_ieee_exceptions, despite the placement of
gen_store_fpr_D, since gen_dest_fpr_D returns cpu_fpr[].

We can simplify the entire implementation by having each
FPOp helper call check_ieee_exceptions.  For the moment this
requires that all FPop helpers write to the TCG global cpu_fsr,
so remove TCG_CALL_NO_WG from the DEF_HELPER_FLAGS_*.

49bb972513 target/sparc: Split ver from env->fsr 
This field is read-only.  It is easier to store it separately
and merge it only upon read.

While we're at it, use FSR_VER_SHIFT to initialize fpu_version.
