Vasileios Kalintiris 48e0256ed6 Re-apply "[mips] Use correct frame register for DWARF info when dynamically realigning the stack."" 
r252219 reversed the direction of subprogram -> function edge. Fixed the
IR to account for this.

Vasileios Kalintiris d38860610d Revert "[mips] Use correct frame register for DWARF info when dynamically realigning the stack." 
This reverts commit r252882. LLParser complains for invalid field 'function'
in DISubprogram.

Vasileios Kalintiris 352eb55baf [mips] Use correct frame register for DWARF info when dynamically realigning the stack. 
Summary:
This patch overrides TargetFrameLowering::getFrameIndexReference() in order to
specify the correct register when the function needs dynamic stack realignment.
The values returned from this function are used in order to create DW_AT_locations
for DWARF info. These locations would use the wrong registers as it's been
reported in PR25028.
