19cbd87c14 target-i386: Rename XMM_[BWLSDQ] helpers to ZMM_*
They are helpers for the ZMMReg fields, so name them accordingly.

This is just a global search+replace, no other changes are being
introduced.

5bde14078d target-i386: update fp status fix
This patch introduces cpu_set_fpuc() function, which changes fpuc field
of the CPU state and calls update_fp_status() function.
These calls update status of softfloat library and prevent bugs caused
by non-coherent rounding settings of the FPU and softfloat.

v2 changes:
 * Added missed calls and intoduced setter function (as suggested by TeLeMan)

f08b617018 softmmu: introduce cpu_ldst.h
This will collect all load and store helpers soon.  For now
it is just a replacement for softmmu_exec.h, which this patch
stops including directly, but we also include it where this will
be necessary in order to simplify the next patch.

2ef6175aa7 tcg: Invert the inclusion of helper.h
Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h.  This
minimizes the files that must be rebuilt when changing the macros
for file N.

d3eb5eaeb5 x86: avoid AREG0 for FPU helpers
Make FPU helpers take a parameter for CPUState instead
of relying on global env.

Introduce temporary wrappers for FPU load and store ops. Remove
wrappers for non-AREG0 code. Don't call unconverted helpers
directly.
