std.Target: Don't match big endian architectures in Arch.toCoffMachine(). 
All of these were mapping to types that are little endian. In fact, I can find
no evidence that either Windows or UEFI have ever been used on big endian
systems.

std.Target: Fix Arch.toElfMachine() for mips. 
EM_MIPS_RS3_LE is obsolete; all mips targets just use EM_MIPS.

Also, fun fact: EM_MIPS_RS3_LE is actually big endian!

9be10ea964 Watch.zig: fixes for windows implementation 
Using --watch I noticed a couple of issues with my initial attempt. 1) The index I used as 'completion key' was not stable over time, when directories are being added/removed the key no longer corresponds with the intended dir. 2) There exists a race condition in which we receive a completion notification for a directory that was removed. My solution is to generate a key value and associate it with each Directory.

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.
