0b0c8734f3 Improve #if support in, and add #assert to, c-pp. Rename target=... preprocessor symbols to target:... because changes in the semantics for symbols which have an '=' makes some of those #if blocks mutually exclusive (which we won't want in rare cases involving the bundler-friendly builds).

80d74f0934 In the regexp extension, limit the maximum value of integers in the 
"{p,q}" syntax, as performance of the NFA used to do pattern matching
is linear in the maximum such integer.  The limit is SQLITE_MAX_REGEXP_REPEAT
which defaults to 999.  This helps to prevent DoS attacks in systems that
make use of the regexp extension.

a4476ea1fa Overhaul the wasm build to (A) support more coexisting variants, e.g. 32/64-bit of both vanilla and esm, and (B) build each variant to its own subdir so that they can build in parallel. It can, with make -j4, now build all new variants in half the time it previously took for just the 32-bit builds. The new build logging output, though unconventional, serves two purposes: (A) improve my build-time situational awareness and (B) it help demystify some of the build steps and output files.
