For a sense of scale, here are the number of mozilla-central warnings
for some clang diagnostics (disabled by default) related to integer
signedness and narrowing:
19,332 -Wsign-conversion warnings about implicit conversions that change
signedness.
12,373 -Wshorten-64-to-32 warnings about 64-bit ints narrowed to 32 bits.
2,701 -Wimplicit-int-conversion warnings about 16, 32, or 64-bit ints
narrowed to 16 or 8 bits.
