std: simplify utf8ToUtf16Le 
Also faster, on my machine unicode/throughput_test.zig now gives e.g.
> original utf8ToUtf16Le: elapsed: 1048 ns (0 ms)
> new utf8ToUtf16Le: elapsed: 971 ns (0 ms)

std: optimise utf8ByteSequenceLength 
Also tested (but not as fast):
```zig
pub fn utf8ByteSequenceLength(first_byte: u8) !u3 {
    const len = @clz(u8, ~first_byte);
    if (len == 0) return 1;
    if (len < 4) return @intCast(u3, len);
    return error.Utf8InvalidStartByte;
}
```

std: add warm up phase to benchmark 
In my tests, whatever ran first was getting much better numbers.
Additionally, add alignment requirements so that comparison is fair.

sentinel slicing improvements 
* add runtime safety for slicing pointers, arrays, and slices.
 * slicing without a sentinel value results in non-sentineled slice
 * improved `std.debug.panic` handling of panic-during-panic

expose the ability to disable C sanitization 
and disable C sanitization when building libcs.
Empirically, they seem to trigger undef-sanitization.

170de5ecae generated docs: log trace instead of error 
When the error occurred for getValueText it could potentially omit
useful documentation since the page stops rendering.

Merge branch 'shawnl-lessThan' 
* always allow integer comparison operations no matter the
   bit width, signedness, or comptime-ness of operands.
   closes #2133

std: lessThan and greaterThan between signed and unsigned 
It is a deviation from C, but I think we should consider making this the behavior
of the operators. See #2133

Revert "Use eventfd in ChildProcess on Linux" 
This reverts commit b169f7b0d51fa9e7cf570479079369b9736093ff.

This caused `integer cast truncated bits` at
std/child_process.zig:801:12

Can be reproduced on my machine simply by running `make`.

un-special-case startup code in the std lib 
Previously, the compiler had special logic to determine whether to
include the startup code, which was in `std/special/start.zig`. Now,
the file is moved to `std/start.zig`, and there is no special logic
in the compiler. Instead, the standard library unconditionally imports
the `start.zig` file, which then has a `comptime` block that does the
logic of determining what, if any, start symbols to export. Instead of
`start.zig` being in its own special package, it is just another normal
file that is part of the standard library.

`std.builtin.TestFn` is now part of the standard library rather than
specially generated by the compiler.
