[llvm][DebugInfo] Emit 0/1 for constant boolean values (#151225)
Previously, sign-extending a 1-bit boolean operand in `#DBG_VALUE` would
convert `true` to -1 (i.e., 0xffffffffffffffff). However, DWARF treats
booleans as unsigned values, so this resulted in the attribute
`DW_AT_const_value(0xffffffffffffffff)` being emitted. As a result, the
debugger would display the value as `255` instead of `true`.

This change modifies the behavior to use zero-extension for 1-bit values
instead, ensuring that `true` is represented as 1. Consequently, the
DWARF attribute emitted is now `DW_AT_const_value(1)`, which allows the
debugger to correctly display the boolean as `true`.
