Currently the instruction paddi always takes s34imm as the type for the

not produce the same fixup as the non PC Relative form.
This patch splits the s34imm type into s34imm and s34imm_pcrel so that two
different fixups can be emitted.

Summary:
In preparation for GlobalISel, PPCSubTarget needs to be renamed to Subtarget as there places in GlobalISel that assume the presence of the variable Subtarget.
This patch introduces the variable Subtarget, and replaces all existing uses of PPCSubTarget with Subtarget. A subsequent patch will remove the definiton of
PPCSubTarget, once any downstream users have the opportunity to rename any uses they have.

A previous patch should have added pld and pstd and any support code in

This patch adds a number of additional prefixed load and store type
instructions for the future CPU.
Differential Revision: https://reviews.llvm.org/D72577
Add the prefixed instructions pld and pstd to future CPU. These are load and
store instructions that require new operand types that are 34 bits. This patch
adds the two instructions as well as the operand types required.
Note that this patch also makes a minor change to tablegen to account for the
fact that some instructions are going to require shifts greater than 31 bits
for the new 34 bit instructions.
Differential Revision: https://reviews.llvm.org/D72574
Future CPU will include support for prefixed instructions.
These prefixed instructions are formed by a 4 byte prefix
immediately followed by a 4 byte instruction effectively
making an 8 byte instruction. The new instruction paddi
is a prefixed form of addi.
This patch adds paddi and all of the support required
for that instruction. The majority of the patch deals with
supporting the new prefixed instructions. The addition of
paddi is mainly to allow for testing.
