Translate enum types as the underlying integer type. Translate enum constants
as top-level integer constants of the correct type (which does not necessarily
match the enum integer type).
If an enum constant's type cannot be translated for some reason, omit it.

* Remove parser error on double ampersand
* Add failing test for double ampersand case
* Add error when encountering double ampersand in AstGen
"Bit and" operator should not make sense when one of its operands
is an address.
* Check that 2 ampersands are adjacent to each other in source string
* Remove cases of unused variables in tests
Instead require `1e9` and `0x1p9`, disallowing the trailing dot.
This change to the grammar is consistent with forbidding `1.` and `0x1.`
as float literals and ensures there is only one way to do things here.
* Extracts AstGen logic from ir.cpp into astgen.cpp. Reduces the
largest file of stage1 from 33,551 lines to 25,510.
* tokenizer: rework it completely to match the stage2 tokenizer logic.
They can now be maintained together; when one is changed, the other
can be changed in the same way.
- Each token now takes up 13 bytes instead of 64 bytes. The tokenizer
does not parse char literals, string literals, integer literals,
etc into meaningful data. Instead, that happens during parsing or
astgen.
- no longer store line offsets. Error messages scan source
files to find the line/column as needed (same as stage2).
- main loop: instead of checking the loop, handle a null byte
explicitly in the switch statements. This is a nice improvement
that we may want to backport to stage2.
- delete some dead tokens, artifacts of past syntax that no longer
exists.
* Parser: fix a TODO by parsing builtin functions as tokens rather than
`@` as a separate token. This is how stage2 does it.
* Remove some debugging infrastructure. These will need to be redone,
if at all, as the code migrates to match stage2.
- remove the ast_render code.
- remove the IR debugging stuff
- remove teh token printing code

We're going to want to improve the stage2 test harness to print
the source file name when a compile error occurs otherwise std lib
contributors are going to see some confusing CI failures when they cause
stage2 AstGen compile errors.

- this one might be problematic; start.zig looks for `main` in the
root source file, not `_main`. Not sure why there is an underscore
there in master branch.
* for cross testing stage2 tests, we use `darling shell` command
since the path to the tested binary is relative to cwd
* for the `zig test` command, we simply use `darling` since the
path to the binary is absolute

Mainly I wanted Jakub's new macOS code for respecting stack size, since
we now depend on it for debug builds able to pass one of the test cases
for recursive comptime function calls with `@setEvalBranchQuota`.
The conflicts were all trivial.
The CPU detection code is nearly at feature parity, we do support
detecting the native CPU on Sparc systems and macos, our ARM/AArch64
model list is quite comprehensive and so is our PPC one.
The only missing pieces are:
- ARM32 detection on Darwin hosts (I don't think anybody is planning on
running the compiler on a old-ass iPhone)
- s390x detection on Linux hosts, this can be easily added at a later
stage.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
The presence of a trailing comma in the single and only input/output
declaration confused the parser and made zig fmt discard any element
placed after the comma.
There are some small problems here and there, mostly due to the pointers
having the lsb set and disrupting the fn alignment tests and the
`@FrameSize` implementation.
