In this case, essentially it is soft float with different library routines.
The next step will be to make this fully interoperational with mips32 floating
point and that requires creating stubs for functions with signatures that
contain floating point types.

I have a more sophisticated design for mips16 hardfloat which I hope to
implement at a later time that directly does floating point without the need
for function calls.

The mips16 encoding has no floating point instructions so one needs to
switch to mips32 mode to execute floating point instructions.

immediate generates the narrow version.  Needed when doing round-trip
assemble/disassemble testing using the alternate syntax that specifies
'pc' directly.

Add back FoldOpIntoPhi optimizations with fix. Included test cases to help catch these errors and to test the presence of the optimization itself

for TLS dynamic models on 64-bit PowerPC ELF.  The default sort routine
for relocations only sorts on the r_offset field; but with TLS, there
can be two relocations with the same r_offset.  For PowerPC, this patch
sorts secondarily on descending r_type, which matches the behavior
expected by the linker.

Add more reset methods to make all objects that the backend may use for outputting code have a reset, some are not used but were declared for completeness

for a wider range of GOT entries that can hold thread-relative offsets.
This matches the behavior of GCC, which was not documented in the PPC64 TLS
ABI.  The ABI will be updated with the new code sequence.

Former sequence:

  ld 9,x@got@tprel(2)
  add 9,9,x@tls

New sequence:

  addis 9,2,x@got@tprel@ha
  ld 9,x@got@tprel@l(9)
  add 9,9,x@tls

Note that a linker optimization exists to transform the new sequence into
the shorter sequence when appropriate, by replacing the addis with a nop
and modifying the base register and relocation type of the ld.

Just give a shout if this was actually still important....

Origin address is always 4 byte aligned, and the access type is always i32.

and we won't likely need this reminder.

If anyone has better highlights (I'm obviously biased by the things that
I'm excited about) jump in and add them!

This change moves the code for default shadow propagaition (handleShadowOr)
and origin tracking (setOriginForNaryOp) into a new builder-like class. Also
gets rid of handleShadowOrBinary.

directly, and the setIsInsideBundle() function will disappear soon.
