Data.LLVM.IR.Builders

LLVM IR builder functions for constructing LLVM IR programmatically.

This module provides convenient builder functions for creating LLVM IR constructs
with sensible defaults and optional parameters. The builders cover:

- **Terminator operations**: switch, invoke, unreachable, etc.
- **Arithmetic operations**: add, sub, mul, div, rem with overflow/exact flags
- **Bitwise operations**: and, or, xor, shift operations
- **Comparison operations**: icmp, fcmp with different predicates
- **Memory operations**: alloca, load, store with various flags
- **Type conversion**: trunc, zext, sext, bitcast, fp conversions
- **Vector operations**: insert/extract/shuffle elements
- **Aggregate operations**: insert/extract values from structs/arrays
- **Control flow**: phi nodes, select, freeze
- **Type shortcuts**: i1, i8, i16, i32, i64, ptr, float, double
- **Constant builders**: integers, booleans, strings, arrays, etc.

All builder functions use default arguments where sensible to reduce verbosity
while still allowing full customization when needed.
