This change is the Zig counterpart to https://reviews.llvm.org/D110413
Since we lower some libcalls directly (just like clang does), we need to
make sure that the ABI we call with matches the ABI of the compiler-rt
we are providing (and also the ABI expected by LLVM).
While I was at it, I noticed some flawed vector handling in the binary
soft float ops in stage 1, so I shored up the logic a bit and expanded
an existing test to cover the missing functionality.
Starting with LLVM 14, the Libcalls to these functions are now lowered
using a Vec(2, u64) instead of the standard ABI for i128 integers, so
our compiler-rt implementation needs to be updated to expose the same
ABI on Windows.
This is intended to fix this error:
lld-link: error: undefined symbol: _GUID const& __mingw_uuidof<IEnumSetupInstances>()

Thank you to Martin Storsjö for suggesting the fix.
This commit adds support for initializing `.anon_struct` types. There
is also some follow-up work to do for both tuples and structs regarding
comptime fields, so this also adds some tests to keep track of that
work.
Key blinding allows public keys to be augmented with a secret
scalar, making multiple signatures from the same signer unlinkable.

This is required by privacy-preserving applications such as Tor
onion services and the PrivacyPass protocol.
The previous code here was potentially more optimal for some cases,
however, I never tested the perf, so it might not actually matter. This
code handles more cases. We can go back and re-evaluate that other
implementation if it seems worthwhile in the future.
This accomplishes two things:
* Works around #8442 by putting stage1-specific logic in to disable all
the std.json tests.
* Slightly reduces installation size of zig since std lib files ending
in "test.zig" are excluded from being installed.
