LemonBoy 42652c1d6e [Sparc] Fixes for the internal assembler
* Prevent the generation of invalid shift instructions by constraining
  the immediate field. I've limited the shift field to constant values
  only, adding the `R_SPARC_5`/`R_SPARC_6` relocations is trivial if
  needed (but I can't really think of a use case for those).
* Fix the generation of PC-relative `call`
* Fix the transformation of `jmp sym` into `jmpl`
* Emit fixups for simm13 operands

I moved the choice of the correct relocation into the code emitter as I've
seen the other backends do, it can be definitely cleaner but the aim was
to reduce the scope of the patch as much as possible.

Fixes the problems raised by joerg in L254199

Fangrui Song aa708763d3 [MC] Add parameter `Address` to MCInstPrinter::printInst
printInst prints a branch/call instruction as `b offset` (there are many
variants on various targets) instead of `b address`.

It is a convention to use address instead of offset in most external
symbolizers/disassemblers. This difference makes `llvm-objdump -d`
output unsatisfactory.

Add `uint64_t Address` to printInst(), so that it can pass the argument to
printInstruction(). `raw_ostream &OS` is moved to the last to be
consistent with other print* methods.

The next step is to pass `Address` to printInstruction() (generated by
tablegen from the instruction set description). We can gradually migrate
targets to print addresses instead of offsets.

In any case, downstream projects which don't know `Address` can pass 0 as
the argument.

Richard Trieu 03fe9d82c4 [Sparc] Move InstPrinter files to MCTargetDesc. NFC
For some targets, there is a circular dependency between InstPrinter and
MCTargetDesc.  Merging them together will fix this.  For the other targets,
the merging is to maintain consistency so all targets will have the same
structure.
