Untangle the logic so the preparation of operands and actual assembling
(branch range checking included) are properly separated, making future
changes easier to review and maintain. No functional change intended.

The LoongArch ELF psABI v2.00 revamped the relocation design, largely
moving to using the `pcalau12i + addi/ld/st` pair for PC-relative
addressing within +/- 32 bits. The "pcala" in `pcalau12i` stands for
"PC-aligned add"; the instruction's semantics happen to coincide with
arm64's `adrp`.
Add support for emitting this instruction as part of the relevant
addressing ops, for use with new reloc types later.

Instruction formats: rdtime rd, rj
The RDTIME family of instructions are used to read constant frequency timer
information, the stable counter value is written into the general register
rd, and the counter id information is written into the general register rj.
(Note: both of its register operands are outputs).

Implemented an assembler for LoongArch64(loong64 is short name) -
this provides register definitions and instruction encoding as
defined in the LoongArch Instruction Set Manual.
