c09324483c Fix broken asserts that never fire. 
Change assert("text") to assert(0 && "text").  The first case is a const char *
to bool conversion, which always evaluates to true, never triggering the
assert.  The second case will always trigger the assert.

0187e7a9ba DebugInfo: remove target-specific Frame Index handling for DBG_VALUE MachineInstrs 
Frame index handling is now target-agnostic, so delete the target hooks
for creation & asm printing of target-specific addressing in DBG_VALUEs
and any related functions.

b86a0cdb67 Machine Model: Add MicroOpBufferSize and resource BufferSize. 
Replace the ill-defined MinLatency and ILPWindow properties with
with straightforward buffer sizes:
MCSchedMode::MicroOpBufferSize
MCProcResourceDesc::BufferSize

These can be used to more precisely model instruction execution if desired.

Disabled some misched tests temporarily. They'll be reenabled in a few commits.

6e0b2a0cb0 Order CALLSEQ_START and CALLSEQ_END nodes. 
Fixes PR16146: gdb.base__call-ar-st.exp fails after
pre-RA-sched=source fixes.

Patch by Xiaoyi Guo!

This also fixes an unsupported dbg.value test case. Codegen was
previously incorrect but the test was passing by luck.

4a971705bc Remove the MachineMove class. 
It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.

I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

667754e239 Remove code copied from GenRegisterInfo.inc.

into a .cpp. It sets a bad example for those working on other targets
and trying to understand the register info API.

700ed80d3d Move the eliminateCallFramePseudoInstr method from TargetRegisterInfo 
to TargetFrameLowering, where it belongs. Incidentally, this allows us
to delete some duplicated (and slightly different!) code in TRI.

There are potentially other layering problems that can be cleaned up
as a result, or in a similar manner.

The refactoring was OK'd by Anton Korobeynikov on llvmdev.

Note: this touches the target interfaces, so out-of-tree targets may
be affected.
