Make the code used to calculate the variable slot index into the frame
match what's done during the structure layout calculation.
Prevents a few nasty LLVM errors when such types are passed around.
The mismatch between the argument slot type in the frame structure and
the one used in the store operation made the generated code write
garbage over the nearby fields.
Fixes#7104
Explicit and implicit integer casts on vector types are now supported
and follow the same rules as their scalar counterparts.
Implicit float casts are accidentally supported, `@floatCast` is still
not vector-aware.
Pay close attention to the RHS type alignment when rendering an
assignment op as it may differ from the LHS pointer one.
This problem was noticed when debugging a CI failure in #6648: due to
sheer luck the misalignment caused a segfault on macos that was also
reproduced locally.
I tried to write a small test case but it turned out to be a daunting
task as I couldn't manage to trigger the problem consistently (and stop
the optimizer from simplifying everything). Patches welcome.

Master branch renamed an enum; this branch gave it an explicit tag type
and explicitly initialized values. This commit combines the changes
together.

The llvm11 branch changed 10's to 11's and master branch added the
"using LLVM_CONFIG_EXE" help message, so the resolution was to merge
these changes together.
I also added a check to make sure LLVM is built with AVR enabled, which
is no longer an experimental target.
These CLI options are now forwarded to the stage1 backend.
We're not going to support the -mllvm CLI option any longer. As a
compromise, we unconditionally tell LLVM to output intel x86 syntax when
using -femit-asm.
Simplify stage1 logic; it no longer has the concept of an output
directory. --output-dir is no longer a valid CLI option. cmake uses
the `-femit-bin=[path]` option.
Note the changes to test/cli.zig. This breaks the CLI API that Godbolt
is using so we're going to want to open a PR to help them upgrade to the
new CLI for the upcoming Zig 0.7.0 release.
