a7da90071e stage2: fix bug in genArg 
When an argument is unused in the function body, still increment
arg_index so we still select the correct arguments in the args slice.

a0ad2dee6a builtin: Add zig_version 
This will enable code to perform version checks and make it easier to
support multiple versions of Zig.

Within the SemVer implementation, an intermediate value needed to be
coerced to a slice to workaround a comptime bug.

Closes #6466

56c059077c stage2: add initial impl of control flow in LLVM backend 
The following TZIR instrutions have been implemented in the backend:
- all cmp operators (lt, lte, gt, gte, eq, neq)
- block
- br
- condbr

The following LLVMIR is generated for a simple assert function:
```
define void @assert(i1 %0) {
Entry:
  %1 = alloca i1, align 1
  store i1 %0, i1* %1, align 1
  %2 = load i1, i1* %1, align 1
  %3 = xor i1 %2, true
  br i1 %3, label %Then, label %Else

Then:                                             ; preds = %Entry
  call void @llvm.debugtrap()
  unreachable

Else:                                             ; preds = %Entry
  br label %Block

Block:                                            ; preds = %Else
  ret void
}
```

See tests for more examples.

3715ed7b54 stage2: implement TZIR printing for block and condbr 
Zig code:
```
fn assert(ok: bool) void {
    if (!ok) unreachable;
}
```

TZIR:
```
Module.Function(name=assert):
  @0: void = {};
  %0: bool = arg(ok)
  %1: void = dbg_stmt()
  %2: void = block(
    %3: bool = not(%0)
    %4: noreturn = condbr(%3,
    then:
      %5: void = breakpoint()
      %6: noreturn = unreach()
    else:
      %7: noreturn = br(%2, @0)
    )
  )
  %8: noreturn = retvoid()
```

31802c6c68 remove z/Z format specifiers 
Zig's format system is flexible enough to add custom formatters.  This PR removes the new z/Z format specifiers that were added for printing Zig identifiers and replaces them with custom formatters.

36950815a4 stage2 test: make sure to pass the dynamic linker to Compilation 
Because this was not set, the `-dynamic-path` argument was not passed
to LLD when linking an ELF binary. This would still generate a valid glibc
binary, however when executing would result in a segfault.

ce5222d945 ci: rework linux script 
* no longer depend on apt.llvm.org, instead we rely on a zig-bootstrap
   tarball with pre-built Zig, LLVM, LLD, and Clang. Similar to the
   Windows Dev Kit but for Linux. This also makes the script no longer
   depend on Docker, libxml2, or GCC.
 * remove bash retry logic; it was only needed for flaky apt.llvm.org
   and isn't needed for the other resources we download.
 * build and upload the experimental std lib automatically generated
   docs. langref.html is moved to docs/langref.html because the std lib
   docs are in docs/std/.
 * the superfluous "zig" directory in $prefix/lib/zig/std/std.zig is
   removed from the tarball.
 * update_download_page makes a commit in the www.ziglang.org repository
   updating data/releases.json so that repository can manage deploys.

LRESULT and LPARAM are currently typedef'd as ?*c_void, however, they are supposed to be typedef'd as LONG_PTR which is equivalent to isize in Zig.

5d5db833f2 stage2: hoist alloca instructions to top of function in LLVM backend 
This way the generated code only has to setup the stack size at the
beginning of a function and this improves codegen.

Fixes #7689

```
fn foo() void {}

export fn hello(z: i8) void {
    var x: i16 = undefined;
    foo();
    var y: i32 = 1;
    y += z;
}
```
llvm-ir:
```
define void @hello(i8 %0) {
Entry:
  %1 = alloca i8, align 1
  %2 = alloca i16, align 2
  %3 = alloca i32, align 4
  store i8 %0, i8* %1, align 1
  %4 = load i8, i8* %1, align 1
  store i16 undef, i16* %2, align 2
  call void @foo()
  store i32 1, i32* %3, align 4
  %5 = load i32, i32* %3, align 4
  %6 = sext i8 %4 to i32
  %7 = add nsw i32 %5, %6
  store i32 %7, i32* %3, align 4
  ret void
