elf: re-use old atom slot for a trampoline to that atom
...
This is the initial implementation of Jacob Young's idea of
re-using old function slots as trampolines for new function's
location. This way the trampoline is guaranteed to be aligned
to the function's alignment.
The only edge case is if an incremental update further overaligns
the function in which case we skip/delete the trampoline and
re-evaluate all references.

build/test: Add a test-modules step for running all the per-target tests.
...
This is useful during porting work where you're mainly concerned with tests that
e.g. run under QEMU. Combine with the new -Dtest-target-filter for an even more
streamlined workflow.

build/test: Add -Dtest-slow-targets and move mips module tests behind it.
...
The idea is that these tests are just too slow to include by default on a
contributor's local machine. If they want to run these, they need to opt in.

std.debug.Dwarf: better source location information
...
Two fixes here:
Sort by addresses after generating the line table. Debug information in
the wild is not sorted and the rest of the implementation requires this
data to be sorted.
Handle DW.LNE.end_sequence correctly. When I originally wrote this code,
I misunderstood what this opcode was supposed to do. Now I understand
that it marks the *end* of an address range, meaning the current address
does *not* map to the current line information.
This fixes source location information for a big chunk of ReleaseSafe
code.

ZigLLVMTargetMachineEmitToFile: put sanitizers in registerOptimizerLastEPCallback

registerOptimizerEarlyEPCallback because I thought clang was doing that,
but I see now it is behind the flag `--sanitizer-early-opt-ep` which is
disabled by default.

std.debug.Coverage.resolveAddressesDwarf: fix broken logic
...
The implementation assumed that compilation units did not overlap, which
is not the case. The new implementation uses .debug_ranges to iterate
over the requested PCs.
This partially resolves #20990 . The dump-cov tool is fixed but the same
fix needs to be applied to `std.Build.Fuzz.WebServer` (sorting the PC
list before passing it to be resolved by debug info).
I am observing LLVM emit multiple 8-bit counters for the same PC
addresses when enabling `-fsanitize-coverage=inline-8bit-counters`. This
seems like a bug in LLVM. I can't fathom why that would be desireable.
