Francis Visoiu Mistrih e4fae4d5b6 [CodeGen] Don't omit any redundant information in -debug output 
In r322867, we introduced IsStandalone when printing MIR in -debug
output. The default behaviour for that was:

1) If any of MBB, MI, or MO are -debug-printed separately, don't omit any
redundant information.

2) When -debug-printing a MF entirely, don't print any redundant
information.

3) When printing MIR, don't print any redundant information.

I'd like to change 2) to:

2) When -debug-printing a MF entirely, don't omit any redundant information.

Francis Visoiu Mistrih 0b5bdceabf [CodeGen] Print stack object references as %(fixed-)stack.0 in both MIR and debug output 
Work towards the unification of MIR and debug output by printing
`%stack.0` instead of `<fi#0>`, and `%fixed-stack.0` instead of
`<fi#-4>` (supposing there are 4 fixed stack objects).

Only debug syntax is affected.

Francis Visoiu Mistrih a8a83d150f [CodeGen] Use MachineOperand::print in the MIRPrinter for MO_Register. 
Work towards the unification of MIR and debug output by refactoring the
interfaces.

For MachineOperand::print, keep a simple version that can be easily called
from `dump()`, and a more complex one which will be called from both the
MIRPrinter and MachineInstr::print.

Add extra checks inside MachineOperand for detached operands (operands
with getParent() == nullptr).

Francis Visoiu Mistrih 93ef145862 [CodeGen] Print "%vreg0" as "%0" in both MIR and debug output 
As part of the unification of the debug format and the MIR format, avoid
printing "vreg" for virtual registers (which is one of the current MIR
possibilities).

Basically:

* find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E "s/%vreg([0-9]+)/%\1/g"
* grep -nr '%vreg' . and fix if needed
* find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E "s/ vreg([0-9]+)/ %\1/g"
* grep -nr 'vreg[0-9]\+' . and fix if needed

it makes sense. Also establish the pattern of simply referencing

Arnold Schwaighofer f54b73d681 ScheduleDAGInstrs: In functions with tail calls PseudoSourceValues are not non-aliasing distinct objects 
The code that builds the dependence graph assumes that two PseudoSourceValues
don't alias. In a tail calling function two FixedStackObjects might refer to the
same location. Worse 'immutable' fixed stack objects like function arguments are
not immutable and will be clobbered.

Change this so that a load from a FixedStackObject is not invariant in a tail
calling function and don't return a PseudoSourceValue for an instruction in tail
calling functions when building the dependence graph so that we handle function
arguments conservatively.

Fix for PR23459.
