664e3e16fa riscv: add cmp_eq MIR instruction 
this opens up the door for addition!

3ccf0fd4c2 riscv: basic struct field access 
the current implementation only works when the struct is in a register. we use some shifting magic
to get the field into the LSB, and from there, given the type provenance, the generated code should
never reach into the bits beyond the bit size of the type and interact with the rest of the struct.

2be3033acd riscv: implement basic branching 
we use a code offset map in Emit.zig to pre-compute what byte offset each MIR instruction is at. this is important because they can be
of different size

28df64cba4 riscv: implement @abs 
- add the `abs` MIR instruction
- implement `@abs` by shifting to the right by `bits - 1`, and xoring.

5e770407cf riscv: basic function arguments 
- rename setRegOrMem -> setValue
- a naive method of passing arguments by register
- gather the prologue and epilogue and generate them in Emit.zig. this is cleaner because we have the final stack size in the emit step.
- define the "fa" register set, which contains the RISC-V calling convention defined function argument registers

f71f27bcb0 Avoid unnecessary operation in PageAllocator. 
There's no need to call `alignForward` before `VirtualAlloc`.
From [MSDN](https://learn.microsoft.com/en-us/windows/win32/api/memoryapi/nf-memoryapi-virtualalloc):
```
If the lpAddress parameter is NULL, this value is rounded up to the next page boundary

708894cf99 add a debug subcommand for printing LLVM integer type alignment 
Useful when debugging why upgrading from LLVM 17 to 18 caused C ABI
regressions. Turns out LLVM 18 does the following insane thing:

6730b366a0 LLVM backend: no more signext on aarch64

6986d2aca9 x86_64 sysv C ABI: fix f128 param and return types 
Clang 17 passed struct{f128} parameters using rdi and rax, while Clang
18 matches GCC 13.2 behavior, passing them using xmm0.

This commit makes Zig's LLVM backend match Clang 18 and GCC 13.2. The
commit deletes a hack in x86_64/abi.zig which miscategorized f128 as
"memory" which obviously disagreed with the spec.

200e06b239 update maxIntAlignment for x86 to 16 
LLVMABIAlignmentOfType(i128) reports 16 on this target, however the C
ABI uses align(4).

Clang in LLVM 17 does this:

%struct.foo = type { i32, i128 }

Clang in LLVM 18 does this:

%struct.foo = type <{ i32, i128 }>

Clang is working around the 16-byte alignment to use align(4) for the C
ABI by making the LLVM struct packed.
