[PATCH v3 00/20] gdbstub refactor and SVE support (+check-tcg tweaks)

[Alex Bennée]

Hi,

In this update of the SVE support I've addressed the review comments
as well expanding the test cases for SVE. I've included a few fixes
for check-tcg to allow for the inclusion of SVE enabled test cases.
This includes including the userspace ID register test as I needed to
do something similar for the SVE specific test.

I think this is ready to be merged once the tree re-opens.

The following patches need review
  08 - gdbstub extend GByteArray to read register helper
  09 - target arm prepare for multiple dynamic XMLs
  11 - target arm default SVE length to 64 bytes for lin
  12 - target arm generate xml description of our SVE re
  13 - tests tcg add a configure compiler check for ARMv
  14 - target arm don t bother with id_aa64pfr0_read for
  15 - tests tcg aarch64 userspace system register test
  16 - tests tcg ensure we re configure if configure.sh 
  17 - tests guest debug add a simple test runner
  18 - tests tcg aarch64 add a gdbstub testcase for SVE 
  19 - tests tcg aarch64 add SVE iotcl test
  20 - tests tcg aarch64 add test sve ioctl guest debug
