247e4ac3cc dwarf: optimize dwarf parsing for speed
This code is run when printing a stack trace in a debug executable, so
it has to be fast even without compiler optimizations.

Adding a `@panic` to the top of `main` and running an x86_64 backend
compiled compiler goes from `1m32.773s` to `0m3.232s`.

d890e81761 mem: fix ub in writeInt
Use inline to vastly simplify the exposed API.  This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.

6f0198cadb Revert "Merge pull request #17637 from jacobly0/x86_64-test-std"
This reverts commit 0c99ba1eab, reversing
changes made to 5f92b070bf.

This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.
