This helps hiding the LiveRange class which really should be private.

This reverts commit 116234.

It compiled just fine with MSVC and clang...

map one-to-one with the CodeGenInstruction operand number.

leave custom lowerings for later.

Fixes some nightly tests.

virtual registers for those stores since RegAllocFast requires that each live
physreg only be used once.

This fixes PR8357.

Also don't use fast-isel on non-darwin since it's untested.

matching in tblgen to do the predicate operand.

try to match them by name first. If there is no by-name match, fall back to
assuming they are in order (this was the previous behavior).

LocalRewriter.

This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.

it comes back, it will be largely a rewrite, so keeping the old codebase

truncate the stack pointer to 32-bits on a 64-bit machine.

alignment for PPC32/64, avoiding some masking operations.

llvm-gcc expands vaarg inline instead of using the instruction
so it has never hit this.
