target/hexagon: Rename macros.inc -> macros.h.inc

Since commits 139c1837db ("meson: rename included C source files
to .c.inc") and 0979ed017f ("meson: rename .inc.h files to .h.inc"),
EMU standard procedure for included header files is to use *.h.inc.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:

If you do use template header files they should be named with
the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
being included for expansion.

Therefore rename "macros.inc" as "macros.h.inc".

target/hexagon/*.py: clean up used 'toss' and 'numregs' vars

Many Hexagon python scripts call hex_common.get_tagregs(), but only one
call site use the full reg structure given by this function. To make the
code cleaner, let's make get_tagregs() filter out the unused fields
(i.e. 'toss' and 'numregs'), properly removed the unused variables at
the call sites. The hex_common.bad_register() function is also adjusted
to work exclusively with 'regtype' and 'regid' args. For the single call
site that does use toss/numregs, we provide an optional parameter to
get_tagregs() which will restore the old full behavior.

Hexagon (target/hexagon/*.py): raise exception on reg parsing error

Currently, the python scripts used for the hexagon building will not
abort the compilation when there is an error parsing a register. Let's
make the compilation properly fail in such cases by rasing an exception
instead of just printing a warning message, which might get lost in the
output.

This patch was generated with:

git grep -l "Bad register" *hexagon* | \
xargs sed -i "" -e 's/print("Bad register parse: "[, ]*\([^)]*\))/hex_common.bad_register(\1)/g'

Plus the bad_register() helper added to hex_common.py.

Hexagon (target/hexagon) Short-circuit packet register writes

In certain cases, we can avoid the overhead of writing to hex_new_value
and write directly to hex_gpr. We add need_commit field to DisasContext
indicating if the end-of-packet commit is needed. If it is not needed,
get_result_gpr() and get_result_gpr_pair() can return hex_gpr.

We pass the ctx->need_commit to helpers when needed.

Finally, we can early-exit from gen_reg_writes during packet commit.

There are a few instructions whose semantics write to the result before
reading all the inputs. Therefore, the idef-parser generated code is
incompatible with short-circuit. We tell idef-parser to skip them.

For debugging purposes, we add a cpu property to turn off short-circuit.
When the short-circuit property is false, we skip the analysis and force
the end-of-packet commit.

Here's a simple example of the TCG generated for
0x004000b4: 0x7800c020 { R0 = #0x1 }

BEFORE:
---- 004000b4
movi_i32 new_r0,$0x1
mov_i32 r0,new_r0

AFTER:
---- 004000b4
movi_i32 r0,$0x1

This patch reintroduces a use of check_for_attrib, so we remove the
G_GNUC_UNUSED added earlier in this series.

Hexagon (target/hexagon) Add v68 scalar instructions

R6_release_st_vi
S2_storew_rl_at_vi
S4_stored_rl_at_vi
S2_storew_rl_st_vi
S4_stored_rl_st_vi

The release instructions are nop's in qemu. The others behave as
loads/stores.

The encodings for these instructions changed some "don't care" bits
L2_loadw_locked
L4_loadd_locked
S2_storew_locked
S4_stored_locked

Merge tag 'pull-hex-20221216-1' of https://github.com/quic/qemu into staging

1)
Performance improvement
Add pkt and insn to DisasContext
Many functions need information from all 3 structures, so merge
them together.

2)
Bug fix
Fix predicated assignment to .tmp and .cur

3)
Performance improvement
Add overrides for S2_asr_r_r_sat/S2_asl_r_r_sat
These functions will not be handled by idef-parser

4-11)
The final 8 patches improve change-of-flow handling.

Currently, we set the PC to a new address before exiting a TB. The
ultimate goal is to use direct block chaining. However, several steps
are needed along the way.

4)
When a packet has more than one change-of-flow (COF) instruction, only
the first one taken is considered. The runtime bookkeeping is only
needed when there is more than one COF instruction in a packet.

5, 6)
Remove PC and next_PC from the runtime state and always use a
translation-time constant. Note that next_PC is used by call instructions
to set LR and by conditional COF instructions to set the fall-through
address.

7, 8, 9)
Add helper overrides for COF instructions. In particular, we must
distinguish those that use a PC-relative address for the destination.
These are candidates for direct block chaining later.

10)
Use direct block chaining for packets that have a single PC-relative
COF instruction. Instead of generating the code while processing the
instruction, we record the effect in DisasContext and generate the code
during gen_end_tb.

11)
Use direct block chaining for tight loops. We look for TBs that end
with an endloop0 that will branch back to the TB start address.

12-21)
Instruction definition parser (idef-parser) from rev.ng
Parses the instruction semantics and generates TCG
