Bob Wilson a625b0110b Remove support for "dregpair" operand modifier, now that it is no longer being 
used for anything.

Jim Grosbach 40e85fbf17 move getRegisterNumbering() to out of ARMBaseRegisterInfo into the helper 
functions in ARMBaseInfo.h so it can be used in the MC library as well.
For anything bigger than this, we may want a means to have a small support
library for shared helper functions like this. Cross that bridge when we
come to it.

Bob Wilson 13ce07fa92 Change ARM VFP VLDM/VSTM instructions to use addressing mode #4, just like 
all the other LDM/STM instructions.  This fixes asm printer crashes when
compiling with -O0.  I've changed one of the NEON tests (vst3.ll) to run
with -O0 to check this in the future.

Prior to this change VLDM/VSTM used addressing mode #5, but not really.
The offset field was used to hold a count of the number of registers being
loaded or stored, and the AM5 opcode field was expanded to specify the IA
or DB mode, instead of the standard ADD/SUB specifier.  Much of the backend
was not aware of these special cases.  The crashes occured when rewriting
a frameindex caused the AM5 offset field to be changed so that it did not
have a valid submode.  I don't know exactly what changed to expose this now.
Maybe we've never done much with -O0 and NEON.  Regardless, there's no longer
any reason to keep a count of the VLDM/VSTM registers, so we can use
addressing mode #4 and clean things up in a lot of places.

Bob Wilson 481d7a9ab4 Rename sat_shift operand to shift_imm, in preparation for using it for other 
instructions besides saturate instructions.  No functional changes.

Johnny Chen 8e8f1c133a Cleaned up the for-disassembly-only entries in the arm instruction table so that 
the memory barrier variants (other than 'SY' full system domain read and write)
are treated as one instruction with option operand.

Bob Wilson b128824b60 Move newlines before inline jumptables from the asm strings in .td files to 
the jtblock_operand print methods.  This avoids extra newlines in the
disassembler's output.  PR7757.

Chris Lattner b792b463af sink the arm implementations of ASmPrinter and MCInstLower 
out of the AsmPrinter directory into libarm.  Now the
ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.

Dale Johannesen b9097a71d4 Make debug info come out in data-only files. 
This is a question of the debugging setup code not
being called at the right time, and it's called from
target-dependent code for some reason.  I have only
attempted to fix Darwin, but I'm pretty sure it's
broken elsewhere; I'll leave that to people who can
test it.

Dale Johannesen 8ef89eabc2 Revert the part of 45849 that treated weak globals 
as weak globals rather than commons.  While not wrong,
this change tickled a latent bug in Darwin's strip,
so revert it for now as a workaround.

Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.
