961b463fad zld: track symbols defined within TextBlock 
in case TextBlock represents an entire section with symbols
defined within.

7aeedc0912 zld: allocate TextBlocks 
temporarily by iterating over all defined TextBlocks. However,
once we merge this with MachO incremental, updates will be done
at the point of creation and/or update.

Also, fix mining TLV knowledge for working out TLV pointers.

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.

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.
