both results with a single div or idiv instruction. This uses new X86ISD
nodes for DIV and IDIV which are introduced during the legalize phase

computations.

Added support for new condition code modeling scheme (i.e. physical register dependency). These are a bunch of instructions that are duplicated so the x86 backend can support both the old and new schemes at the same time. They will be deleted after

Added major new capabilities to scheduler (only BURR for now) to support physical register dependency. The BURR scheduler can now backtrace and duplicate instructions in order to avoid "expensive / impossible to copy" values (e.g. status flag EFLAGS for x86) from being clobbered.

When mixing SSE and x87 codegen, it's possible to
...
have situations where an SSE instruction turns into
multiple blocks, with the live range of an x87
register crossing them. To do this correctly make
sure we examine all blocks when inserting
FP_REG_KILL. PR 1697. (This was exposed by my
fix for PR 1681, but the same thing could happen
mixing x87 long double with SSE.)
