still be OK).
Additionally, some update on the container side recently enabled
OpenGL in these jobs - but the corresponding code fails to compile.
Thus disable OpenGL here for the time being until someone figured

The current docker image for cross compiling hexagon guests
is manually built since it takes >2 hours to build from source.
This patch:
1. Solves the above issue by using the prebuilt clang
toolchain hosted on CodeLinaro [1] and maintained by QUIC [2].
2. The dockerfile is also switched from multi-stage to single stage
build to allow the CI docker engine to reuse the layer cache.
3. Re-enables the hexagon-cross-container job to be always run in
CI and makes it a non-optional dependency for the
build-user-hexagon job.
The changes for 1 & 2 together bring down the build time to
~3 minutes in GitLab CI when cache is reused and ~9 minutes
when cache cannot be reused.

After configuring with --target-list=hexagon-linux-user
running `make check-tcg` just prints the following:
```
make: Nothing to be done for 'check-tcg'
```
In the probe_target_compiler function, the 'break'
command is used incorrectly. There are no lexically
enclosing loops associated with that break command which
is an unspecfied behaviour in the POSIX standard.
The dash shell implementation aborts the currently executing
loop, in this case, causing the rest of the logic for the loop
in line 2490 to be skipped, which means no Makefiles are
generated for the tcg target tests.

Define the DEXCR and HDEXCR as special purpose registers.
Each register occupies two SPR indicies, one which can be read in an
unprivileged state and one which can be modified in the appropriate
priviliged state, however both indicies refer to the same underlying
value.
Note that the ISA uses the abbreviation UDEXCR in two different
contexts: the userspace DEXCR, the SPR index which can be read from
userspace (implemented in this patch), and the ultravisor DEXCR, the
equivalent register for the ultravisor state (not implemented).
