Fix some bugs and relande4c1dfed38and614c63bec6. 1. Run argument stack rebase pass before the reserved physical register is finalized. 2. Add LEA pseudo instruction to prevent the instruction being eliminated. 3. Don't support X32.
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
