Rebase against master

@RKSimon the X86 vaarg codegen tests seem to be passing now with EXPENSIVE_CHECKS enabled

@RKSimon I don't have commit access, would you be able to do this?

• Remove extraneous newline

• Fix indentation

• Add getMachineMemOperand overload for setting flags

Remember other flags when cloning

I've created a separate patch for this assertion

Building this locally with EXPENSIVE_CHECKS enabled causes a large number of warnings in the x86 test:

• • Bad machine code: Missing mayStore flag ***
• function: test_large_vec_vaarg
• basic block: %bb.0 (0x25e70f4da58)
• instruction: %11:gr32 = MOV32rm %stack.0.args, 1, $noreg, 0, $noreg :: (load store 8 on %ir.args)

@RKSimon @shchenz Thanks. I don't have commit rights, would someone else mind landing this instead?

Get alignment from new vector type

Remove stray CHECK

Adding some PowerPC people to double check

Removed endianness swapping and added PowerPC BE/LE test: (I'm not familiar with it: does this look ok?)

Run update_llc_test_checks.py

Add full context to the patch

@jdoerfert Can you commit this?

Hopefully not!
Also just a heads up, I don't have commit access to land this
