72768bddcd std.Build.Fuzz.WebServer: sort pcs before source location lookup

022bca9b06 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.

b5398180d6 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.

d6f9972594 all: Handle spirv in addition to spirv(32,64) where applicable. 
Some of this is arbitrary since spirv (as opposed to spirv32/spirv64) refers to
the version with logical memory layout, i.e. no 'real' pointers. This change at
least matches what clang does.

f6f1ecf0f9 more optimized and correct management of 8-bit PC counters 
* Upgrade from u8 to usize element types.
  - WebAssembly assumes u64. It should probably try to be target-aware
    instead.
* Move the covered PC bits to after the header so it goes on the same
  page with the other rapidly changing memory (the header stats).

depends on the semantics of accepted proposal #19755

closes #20994
