* Added peer type resolution for arrays and vectors: the vector type is
selected.
* Fixed passing the lhs type or rhs type instead of the peer resolved
type when calling Value methods during analyzeArithmetic handling of
comptime expressions.
* `checkVectorizableBinaryOperands` now allows mixing vectors and
arrays, as long as one of the operands is a vector.
This matches stage1's handling of `^=` but apparently stage1 is
inconsistent and does not handle e.g. `*=`. stage2 now will always allow
mixing vector and array operands for all operations.
* Use `@Vector` syntax instead of `std.meta.Vector`.
* Use `var` instead of `const` for tests so that we get runtime
coverage instead of only comptime coverage. Comptime coverage is done
with `comptime doTheTest()` calls.
Notably, Value.eql and Value.hash are improved to treat NaN as equal to
itself, so that Type/Value can be hash map keys. Likewise float hashing
normalizes the float value before computing the hash.
* Sema: fix `zirTypeInfo` allocating with the wrong arenas for some
stuff.
* LLVM: split `airDbgInline` into two functions, one for each AIR tag.
- remove the redundant copy to type_map_arena. This is the first
thing that lowerDebugType does so this hack was probably just
accidentally avoiding UB (which is still present prior to this
commit).
- don't store an inline fn inst into the di_map for the generic
decl.
- use a dummy function type for the debug info to avoid whatever UB
is happening.
- we are now ignoring the function type passed in with the
dbg_inline_begin and dbg_inline_end.
* behavior tests: prepare the vector tests to be enabled one at a time.
Mitigates #11199.
This was an attempt to move saturating_arithmetic.zig to the "passing
for stage2" section, which did not pan out due to the discovery of 2
prerequisite items that need to be done, but I did make a bug fix along
the way of the calculation of max/min integers.
This commit also simplifies the saturating arithmetic behavior tests to
depend on less of the zig language that is not related to saturating
arithmetic.

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.
