2faf8c53d2 macho: use target arch page_size for codesig 
It turns out I was wrong and we can set the page size to the actual
page size used by the target architecture when dividing the binary
into chunks and calculating a hash of each chunk for embedding within
the adhoc code signature. This shaves of a considerable amount of bytes
since we divide the code signature section by at least 2x.

I've also unified the `write` interface of `CodeSignature` struct to
follow that used in every other bit of `MachO`; namely, the functions
now accept a writer instead of a buffer, therefore, there is no need
to manually track where to write each struct field anymore.

5b2a79848c stage2: cleanups regarding red zone CLI flags 
* CLI: change to -mred-zone and -mno-red-zone to match gcc/clang.
 * build.zig: remove the double negative and make it an optional bool.
   This follows precedent from other flags, allowing the compiler CLI to
   be the decider of what is default instead of duplicating the default
   value into the build system code.
 * Compilation: make it an optional `want_red_zone` instead of a
   `no_red_zone` bool. The default is decided by a call to
   `target_util.hasRedZone`.
 * When creating a Clang command line, put -mred-zone on the command
   line if we are forcing it to be enabled.
 * Update update_clang_options.zig with respect to the recent {s}/{} format changes.
 * `zig cc` integration with red zone preference.

e1d8073d2f stage2: add support for loops in LLVM backend 
A simple `while(true) {}` loop generates the following LLVMIR:
```
define i32 @main() {
Entry:
  br label %Loop

Loop:                                 ; preds = %Loop, %Entry
  br label %Loop
}
```

Also implement TZIR printing for loops and add a corresponding test.

a0ad2dee6a builtin: Add zig_version 
This will enable code to perform version checks and make it easier to

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

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.

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
