538d485782 std: Add pow(a,b) for big ints 
Implemented following Knuth's "Evaluation of Powers" chapter in TAOCP,
some extra complexity is needed to make sure there's no aliasing and
avoid allocating too many limbs.

A brief example to illustrate why the last point is important:
consider 10^123, since 10 is well within the limits of a single limb we
can safely say that the result will surely fit in:

⌈log2(10)⌉ bit * 123 = 492 bits = 7 limbs

A naive calculation using only the number of limbs yields:

1 limb * 123 = 123 limbs

The space savings are noticeable.

70f3767903 revert adding std.event.Loop.runDetached 
I'd like to discuss this before adding it. I think this is the wrong
direction to go with this API.

8b4f5f039d Alternative strategy to avoid calling stat() 
This is an optimization as it avoids an extra syscall, but it's also a
workaround for fstat being not available on Windows.

a9b107045f Use load acquire semantics when reading the SQPOLL wakeup flag 
Ensures that the wakeup flag is read after the tail pointer has been
written. It's important to use memory load acquire semantics for the
flags read, otherwise the application and the kernel might not agree on
the consistency of the wakeup flag, leading to I/O starvation.

0f248e0988 std: Make file copy ops use zero-copy mechanisms 
Use copy_file_range on Linux (if available), fcopyfile on Darwin,
sendfile on *BSDs (and on Linux kernels without copy_file_range).

8161de7fa4 Implement ghash aggregated reduction 
Performance increases from ~400 MiB/s to 450 MiB/s at the expense of
extra code. Thus, aggregation is disabled on ReleaseSmall.

Since the multiplication cost is significant compared to the reduction,
aggregating more than 2 blocks is probably not worth it.

f69650a478 update wasm to use ".o.wasm" extension for objects
