At the same time, use ### to separate 3rd-level sections.

4.1.93 Branches, and 4.1.94 Loads and stores.

This includes SCVTF, UCVTF, FCVT{N,P,M,Z,A}{S,U}.
Remove disas_fp_fixed_conv as those were the last insns
decoded by that function.

To: qemu-devel
From: Richard Henderson <richard.henderson@linaro.org>
Remove handle_2misc_64 as these were the last insns decoded
by that function. Remove helper_advsimd_f16to[su]inth as unused;
we now always go through helper_vfp_to[su]hh or a specialized
vector function instead.

Mea culpa, I don't know how I got this wrong in 2dfe93699c. Still
getting used to the new address, I suppose. Somehow I got it right in the
mailmap, though.

target/arm/helper.c is very large and unwieldy. One subset of code
that we can pull out into its own file is the cpreg arrays and
corresponding functions for the TLBI instructions.
Because these are instructions they are only relevant for TCG and we
can make the new file only be built for CONFIG_TCG.
In this commit we move the AArch32 instructions from:
not_v7_cp_reginfo[]
v7_cp_reginfo[]
v7mp_cp_reginfo[]
v8_cp_reginfo[]
into a new file target/arm/tcg/tlb-insns.c.
A few small functions are used both by functions we haven't yet moved
across and by functions we have already moved. We temporarily make
these global with a prototype in cpregs.h; when the move of all TLBI
insns is complete these will return to being file-local.
For CONFIG_TCG, this is just moving code around. For a KVM only
build, these cpregs will no longer be added to the cpregs hashtable
for the CPU. However this should not be a behaviour change, because:
* we never try to migration sync or otherwise include
ARM_CP_NO_RAW cpregs
* for migration we treat the kernel's list of system registers
as the authoritative one, so these TLBI insns were never
in it anyway
The no-tcg stub of define_tlb_insn_regs() therefore does nothing.

To: qemu-devel
Move the AArch32 TLBI insns for AArch32 EL2 to tlbi_insn_helper.c.
To keep this as an obviously pure code-movement, we retain the
same condition for registering tlbi_el2_cp_reginfo that we use for
el2_cp_reginfo. We'll be able to simplify this condition later,
since the need to define the reginfo for EL3-without-EL2 doesn't
apply for the TLBI ops specifically.
This move brings all the uses of tlbimva_hyp_write() and
tlbimva_hyp_is_write() back into a single file, so we can move those
also, and make them file-local again.
The helper alle1_tlbmask() is an exception to the pattern that we
only need to make these functions global temporarily, because once
this refactoring is complete it will be called by both code in
helper.c (vttbr_write()) and by code in tlb-insns.c. We therefore
put its prototype in a permanent home in internals.h.

We currently register the tlbi_el2_cp_reginfo[] TLBI insns if EL2 is
implemented, or if EL3 and v8 is implemented. This is a copy of the
logic used for el2_cp_reginfo[], but for the specific case of the
TLBI insns we can simplify it. This is because we do not need the
"if EL2 does not exist but EL3 does then EL2 registers should exist
and be RAZ/WI" handling here: all our cpregs are for instructions,
which UNDEF when EL3 exists and EL2 does not.
Simplify the condition down to just "if EL2 exists".
This is not a behaviour change because:
* for AArch64 insns we marked them with ARM_CP_EL3_NO_EL2_UNDEF,
which meant that define_arm_cp_regs() would ignore them if
EL2 wasn't present
* for AArch32 insns, the .access = PL2_W meant that if EL2
was not present the only way to get at them was from AArch32
EL3; but we have no CPUs which have ARM_FEATURE_V8 but
start in AArch32
