Add a field '.allocations' to actually track the number of allocations.

Additionally, only increment '.deallocations' when memory is freed

The *Mem variants cannot return EndOfStream and are generally unsafe to

Proper order of checks, try both the variants and make sure they return
the same error/result.

a7346ea49f fix build on macOS 
Sadly due to a workaround for LLD linker limitations on macOS
we cannot put libuserland into an .a file; instead we have to use object
files. Again due to linker limitations, bundling compiler_rt.o into
another relocatable object also doesn't work. So we're left with
disabling stack probing on macOS for the stage1 self-hosted code.

These workarounds could all be removed if the macos support in the LLD
linker improved, or if Zig project had its own linker that did not have
these issues.

add --bundle-compiler-rt function to link options 
and use it when building libuserland.a

The self-hosted part of stage1 relies on zig's compiler-rt, and so we
include it in libuserland.a.

This should potentially be the default, but for now it's behind a linker
option.

self-hosted translate-c: small progress on translating functions.

std.debug: fix stack trace iteration code 
Previously, the stack trace iteration code was using the number of
frames collected as the number of frames to print, not recognizing the
fixed size of the buffer. So it would redundantly print items, matching
the total number of frames ever collected.

Now the iteration code is limited to the actual stack trace frame count,
and will not print duplicate frames.

4ab7b459df Avoid endless recursion in __extendhfsf2 
On some platforms the conversion ended up creating a dangerous recursive
loop that ate all the stack.

The conversion to f16 is also pointless since we're operating on the raw
bits anyway.

std lib sleep APIs: add doc comments and no @intCast 
The sleep APIs are now documented as having spurious wakeups and no
precision of timing guaranteed. They also cannot fail. This commit makes
the entire range of u64 legal values to pass to std.os.time.sleep and
std.os.time.posixSleep. Values that do not fit in the native system APIs
will cause a sleep for the longest possible duration and then be handled
as a spurious wakeup.

cf8dde2d68 std.HashMap: cleanup ensureCapacity + add test 
- Cleaned up some comments
- Removed the "is power of two" check from optimizedCapacity since the * 5 / 3 is unlikely to end up with a power of two, so it's a wasted check the majority of the time
- Made ensureCapacity/ensureCapacityExact increment the modification count if they resize the hash map so that we can catch resizes while iterating, which would likely break the iterator state
