93d1c2d6d4 std: fix compile errors caught by stage2 AstGen

8dd7378013 delete packed enums from the language 
No need for any such thing. Instead, provide an integer tag type for the
enum.

507a8096d2 std: fix compile errors caught by stage2 AstGen 
* `comptime const` is redundant
 * don't use `extern enum`; specify a tag type.
   `extern enum` is only when you need tags to alias. But aliasing tags
   is a smell. I will be making a proposal shortly to remove `extern enum`
   from the language.
 * there is no such thing as `packed enum`.
 * instead of `catch |_|`, omit the capture entirely.
 * unused function definition with missing parameter name
 * using `try` outside of a function or test

6cd71931cb stage1: Unbreak build on FreeBSD 
It turns out that the endianness-detection header delivered with the
softfloat library is extremely brittle and gives wrong results when
targeting FreeBSD (long story short, _BIG_ENDIAN is always defined there
and that breaks the #if defined() chain).

Use our own endianness detection header to work around any potential
problem.

b4baa9eda2 AstGen: try fixups 
Primarily this required fixing `setCondBrPayloadElideBlockStorePtr` to
not assume there would always be two `store_to_block_ptr` instructions
in each of the condbr prongs.

std/crypto: use finer-grained error sets in function signatures (#8558) 
std/crypto: use finer-grained error sets in function signatures

Returning the `crypto.Error` error set for all crypto operations
was very convenient to ensure that errors were used consistently,
and to avoid having multiple error names for the same thing.

The flipside is that callers were forced to always handle all
possible errors, even those that could never be returned by a
function.

This PR makes all functions return union sets of the actual errors
they can return.

The error sets themselves are all limited to a single error.

Larger sets are useful for platform-specific APIs, but we don't have
any of these in `std/crypto`, and I couldn't find any meaningful way
to build larger sets.
