A 64-bit literal can be used as a 32-bit zero or sign extended operand. In case of double zeroes are added to the low 32 bits. Currently asm parser stores only high 32 bits of a double into an operand. To support codegen as requested by the https://github.com/llvm/llvm-project/issues/67781 we need to change the representation to store a full 64-bit value so that codegen can simply add immediates to an instruction. There is some code to support compatibility with existing tests and asm kernels. We allow to use short hex strings to represent only a high 32 bit of a double value as a valid literal.
