LOG: [docs] Regenerate DiagnosticsReference.rst
It looks like it has been a while since the checked-in version of
DiagnosticsReference.rst was regenerated. I realise there probably
isn't any expectation that the checked-in version is kept up-to-date,
but now that the project is on github and the rst can be viewed directly
from the repo's web interface, it seemed worth having something a bit
more recent.

+
+
+The warning is issued if the number of pre-processor tokens exceeds
+the token limit, which can be set in three ways:
+
+1. As a limit at a specific point in a file, using the ``clang max_tokens_here``
+ pragma:
+
+ .. code-block: c++
+ #pragma clang max_tokens_here 1234
+
+2. As a per-translation unit limit, using the ``-fmax-tokens=`` command-line
+ flag:
+
+ .. code-block: console
+ clang -c a.cpp -fmax-tokens=1234
+
+3. As a per-translation unit limit using the ``clang max_tokens_total`` pragma,
+ which works like and overrides the ``-fmax-tokens=`` flag:
+
+ .. code-block: c++
+ #pragma clang max_tokens_total 1234
+
+These limits can be helpful in limiting code growth through included files.
+
+Setting a token limit of zero means no limit.
