The code accidentally used the phdr offset instead of the shdr one while
iterating over the section headers.

61e9e82bdc std: Make the CRC32 calculation slightly faster 
Speed up a little the slicing-by-8 code path by replacing the
(load+shift+xor)*4 sequence with a single u32 load plus a xor.

Before:

```
iterative:  1018 MiB/s [000000006c3b110d]
small keys:  1075 MiB/s [0035bf3dcac00000]
```

After:

```
iterative:  1114 MiB/s [000000006c3b110d]
small keys:  1324 MiB/s [0035bf3dcac00000]
```

5e50d145d9 std: Limit the read/write size on Darwin 
It turns out that the kernel won't read or write more than 0x7fffffff
bytes in a single call, failing with EINVAL when trying to do so.

Adjust the limit and curse whoever is responsible for this.

Closes #6332

41f244bd2f std: Make the DEFLATE decompression routine 3x faster 
A profiler run showed that the main bottleneck was the naive decoding of
the Huffman codes, replacing it with a nice trick borrowed by Zlib gave
a substantial speedup.
Replacing a `%` with a `and (mask-1)` gave another significant
improvement (yay for low hanging fruits).

A few numbers obtained by decompressing a 22M file:

Before:
```
./decompress  2,39s user 0,00s system 99% cpu 2,400 total
```

After:
```
./decompress  0,79s user 0,00s system 99% cpu 0,798 total

std, stage1: make shared library versioning optional 
This commit changes the behavior of stage1 to emit libfoo.so instead
of libfoo.so.0.0.0 when none of the --ver-major, --ver-minor, or
--ver-patch flags are set.

It also makes it possible to create unversioned shared libraries
using the zig build system, changing the version parameter of
addSharedLibrary() to a tagged union.

486a774e5f std: add option to use single-threaded event loop 
std.event.Loop does not yet work in single threaded builds. However,
using evented io on a single thread can be very convenient. This commit
allows settind @import("root").event_loop_mode to .single_threaded
in order to allow this without reimplementing the startup code in
start.zig
