e524f43a6f zld: save rebase and TLV offset as part of TextBlock 
instead of as part of the Symbol. This seems to be more
optimal way of handling dyld ops in presence of no splittable
input sections in object files.

28dd9d478d C backend: TypedefMap is now ArrayHashMap 
The C backend depends on insertion order into this map so that type
definitions will be declared before they are used.

total capacity instead of the current used capactiy.

* remove unused download page html. It's now handled in the

 * add netbsd to the downloads index.json file that we send to
   the www.ziglang.org website repo.
 * shallow clone the website repo to avoid downloading old copies of
   data.js unnecessarily.

aa2a31612f io_uring: add sqe prep methods for epoll_ctl, poll_add, and poll_remove 
Implement io_uring submission queue entry preparation methods for
epoll_ctl, poll_add and poll_remove.

Poll masks are designated as 32-bit little-endian integers as
specified in liburing's definitions.

Updated io_uring_prep_rw to take in an unsigned 64-bit address instead
of an anytype. io_uring_sqe by default assumes that the address
specified in a submission queue entry is an unsigned 64-bit integer.

40764650af stage1: avoid wasting padding with IR instruction tag 
For stage1 ZIR instructions and stage1 AIR instructions, the instruction
op code was taking up 8 bytes due to padding even though it only needed
1 byte. This commit reduces the ref_count field from uint32_t to
uint16_t because the code only really cares if instructions are
referenced at all, not how many times they are referenced. With the
ref_count field reduced to uint16_t the uint8_t op code is now placed in
the freed up space.

Empirically, this saves 382 MiB of peak RAM usage when building the
self-hosted compiler, which is a reduction of 5%. Consequently this
resulted in a 3% reduction of cache-misses when building the self-hosted
compiler.

This was @SpexGuy's idea, committed by me because we tested it on my
computer.
