457dee1a33 Make our <ctype.h> benchmarks less useless. 
Apparently we hadn't looked at the disassembly of these benchmarks since
implementing the various <ctype.h> functions inline, because they've all
been optimized away to literal loads of 0 or 1.

Obviously, this is not helpful when trying to judge further
optimizations.

Test: objdump and ran the benchmarks (on both arm64 and arm32)

0e1412e08e Make memtag_handle_longjmp precise 
We would get the SP inside of memtag_handle_longjmp, which could prevent
us from detecting the case where a longjmp is going into a function that
had already returned. This changes makes the behaviour more predictable.

98731dc343 Revamp the elftls_dl.dtv_resize test 
Split the test out into a separate executable to reduce the number of
ELF modules in the DTV, so that the test can more easily observe the
behavior of loading a module that requires doubling the DTV size. We
want to see the DTV expand from 5 entries (8 words w/header) to
13 entries (16 words w/header).

Make the test work with an initial number of ELF TLS modules between
2 and 4.
