[RFC PATCH v3 00/34] Hexagon patch series

[Taylor Simpson]

This series adds support for the Hexagon processor with Linux user support

See patch 02/34 Hexagon README for detailed information.

Once the series is applied, the Hexagon port will pass "make check-tcg".
The series also includes Hexagon-specific tests in tcg/tests/hexagon.

We have a parallel effort to make the Hexagon Linux toolchain inside a docker
container publically available.

*** Future items under consideration ***
Use qemu softfloat
Use qemu decodetree

*** Known checkpatch issues ***

The following are known checkpatch errors in the series
    target/hexagon/reg_fields.h         Complex macro
    target/hexagon/attribs.h            Complex macro

*** Changes in v3 ***
Remove substantial portions of the code to facilitate review
- Plan to submit subsequent patches
- Hexagon Vector eXtensions (HVX)
- Circular and bit-reverse addressiong
- Add/sub-with-carry
- Unused insn_t and pkt_t fields
- Unused instruction attributes
- All TCG overrides except instructions with multiple definitions
- Unused macros
- Unused reg fields
- COUNT_HEX_HELPERS
Use Laurent's gensyscall.sh script to generate linux-user/hexagon/syscall_nr.h
Handle mem_noshuf
Remove "RsV = RsV" per review feedback
Simplify include file structure
Add directed tests in <qemu>/tests/tcg/hexagon
Rework the python scripts to generate one header file at a time
Change fWRAP_* macros to fGEN_TCG_*

*** Changes in v2 ***
- Use scripts/git.orderfile
