This patch continues a series of patches that decrease time spent by GlobalISel in its InstructionSelect pass by roughly 60% for -O0 builds for large inputs as measured on sqlite3-amalgamation (http://sqlite.org/download.html) targeting AArch64. This commit specifically removes number of operands checks that are redundant if the instruction's opcode already guarantees that number of operands (or more), and also avoids any kind of checks on a def operand of a nested instruction as everything about it was already checked at its use. The expected performance implication is about 3% off InstructionSelect comparing to the baseline (before the series of patches) This patch also contains a bit of NFC changes required for further patches in the series. Every commit planned shares the same Phabricator Review.
