dbc11be038 std: Fix two bugs in bigint pow 
* Correctly scan all the exponent bits, this caused the incorrect result
  to be computed for exponents being powers of two.
* Allocate enough limbs to make llmulacc stop whining.

7f7e2d608a Revert "revert adding std.event.Loop.runDetached" 
This reverts commit 70f37679035e64bacfc4807709da37bc02fbb346.

After discussion, I can see the value provided here, specifically with
avoiding the footgun of defer { suspend { free(@frame()); } }.

However the doc comments are updated to explain the semantics directly,
rather than basing them on the behavior of another programming language.

operator.

e94a06ac29 Build.zig: Skip copying files that are used internally by the compiler 
Before this it was trying to copy all the files from the zig-cache dir
to the output dir, but in the current compiler architecture the cache
dir is also used for internal compiler files.

33bc1ebe37 build system: implement computeOutFilenames using std.zig.binNameAlloc 
See #6552 #6553 #6483

Also fixes a regression introduced in
1d777e99588be047ec4d7650f048b043d6e52da0 of not converting an integer to
a string for a command line parameter.

a927f24201 Generate more MachO exe boilerplate 
* Convert draft to generate all relevant segments and sections in right places
* Do not prealloc space in text blocks until we can NOP
* Write out LC_LOAD_DYLINKER command
* Add LC_LOAD_DYLIB command in order to specify to load libSystem
* Redo update decl exports (similar to Elf globals, globals need to be contiguous in
  memory)

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.

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.
