libgccjit performs numerous checks at the API boundary, but
if these succeed, it ignores errors and other diagnostics emitted
within the core of gcc, and treats the compile of a gcc_jit_context
as having succeeded.
This patch ensures that if any diagnostics are emitted, they
are visible from the libgccjit API, and that the the context is
flagged as having failed.
For now any kind of diagnostic is treated as a jit error,
so warnings and notes also count as errors.

Some patterns are using '%w2' for immediate operands, which means that a zero
immediate is actually emitted as 'wzr' or 'xzr'. This not only changes an
immediate operand into a register operand but may emit illegal instructions
from legal RTL (eg. ORR x0, SP, xzr rather than ORR x0, SP, 0).
