Bharata B Rao c6d8c5ba5a target-ppc: Use ppc_vsr_t.f128 in xscmp[o,u,exp]qp
xscmpoqp, xscmpuqp & xscmpexpqp were added before f128 field was
introduced in ppc_vsr_t. Now that we have it, use it instead of
generating the 128 bit float using two 64bit fields.

Bharata B Rao ffc67420f9 target-ppc: Rename helper_compute_fprf to helper_compute_fprf_float64
Since helper_compute_fprf() works on float64 argument, rename it
to helper_compute_fprf_float64(). Also use a macro to generate
helper_compute_fprf_float64() so that float128 version of the same
helper can be introduced easily later.

Bharata B Rao 855f7a657e target-ppc: Fix xscmpodp and xscmpudp instructions
- xscmpodp & xscmpudp are missing flags reset.
- In xscmpodp, VXCC should be set only if VE is 0 for signalling NaN case
  and VXCC should be set by explicitly checking for quiet NaN case.
- Comparison is being done only if the operands are not NaNs. However as
  per ISA, it should be done even when operands are NaNs.

Bharata B Rao 985e3023f7 target-ppc: Consolidate instruction decode helpers
Move instruction decode helpers to target-ppc/internal.h so that some
of these can be used from outside of translate.c. This movement also
helps to get rid of some duplicate helpers from target-ppc/fpu_helper.c.

Thomas Huth fcf5ef2ab5 Move target-* CPU file into a target/ folder
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
