Currently we only support %z and %ll width modifiers,
but surprisingly not %l. This makes it impossible to print longs
(sizeof(long) not necessary equal to sizeof(size_t)).
We had some printf's that printed longs with %zu,
but that's wrong and now with __attribute__((format)) in place
they are flagged by compiler. So we either have a choice of
doing static_cast<uptr>(long) everywhere or add %l.
Adding %l looks better, that's a standard modifier.

This reverts commits
"sanitizer_common: support printing __m128i type"
and "[sanitizer] Fix VSNPrintf %V on Windows".
Unfortunately, custom "%V" is inherently incompatible with -Wformat,
it produces both:
warning: invalid conversion specifier 'V' [-Wformat-invalid-specifier]
warning: data argument not used by format string [-Wformat-extra-args]
If we disable both of these warnings we lose lots of useful warnings as well.
Depends on D107978.

__m128i is vector SSE type used in tsan.
It's handy to be able to print it for debugging.

See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $(basename $f) . ; done
and manually updated references to renamed files found by that.
