829a3a18d2 ARM does not support offset folding (yet). Disable it for now. 
This fixes PR5031. Unfortunately, there is no small testcase :(

f3eb70e183 PR4047: Permit configure --enable-targets=host,cpp for example. "host" has the 
same effect that "host-only" used to have, but can be combined with other
targets.  host-only is still available as a synonym but no longer documented.

7484864fc3 Fix bug in kill flag updating for post-register-allocation scheduling. When the kill flag of a superreg needs to be cleared because there are one or more subregs live, we instead add implicit-defs of those subregs and leave the kill flag on the superreg. This allows us to end the live-range of the superreg without ending the live-ranges of the subregs.

863ed2677b Fix PR5024. LiveVariables physical register defs should *commit* only after all 
of the defs are processed.
Also fix a implicit_def propagation bug: a implicit_def of a physical register
should be applied to uses of the sub-registers.

8b2d3ef326 Give MachineMemOperand an operator<<, factoring out code from 
two different places for printing MachineMemOperands.

Drop the virtual from Value::dump and instead give Value a
protected virtual hook that can be overridden by subclasses
to implement custom printing. This lets printing be more
consistent, and simplifies printing of PseudoSourceValue
values.

b8a623820a lit: When executing shell scripts internally, don't allow piped stderr on any

06695b3ea1 Add a magic LLVM_DISABLE_CRT_DEBUG environment variable which we check in RegisterHandler and use to disable the Win32 crash dialogs. These are a major blocker to any kind of automated testing.

ac9a646035 Switch FoldingSet::AddString to StringRef based API.

6d5513977b Add a TrackingVH value handle. 
This is designed for tracking a value even when it might move (like WeakVH), but it is an error to delete the referenced value (unlike WeakVH0. TrackingVH is templated like AssertingVH on the tracked Value subclass, it is an error to RAUW a tracked value to an incompatible type.

For implementation reasons the latter error is only diagnosed on accesses to a mis-RAUWed TrackingVH, because we don't want a virtual interface in a templated class.

The former error is also only diagnosed on access, so that clients are allowed to delete a tracked value, as long as they don't use it. This makes it easier for the client to reason about destruction.

ff7fe7f353 Minor bug fix. LowerSubregs should translate 
%S0<def> = EXTRACT_SUBREG %Q0<kill>, 1
to
%S0<def> = IMPLICIT_DEF %Q0<imp-use,kill>

Implicit_def does not *read* any register so the operand should be marked "implicit". The missing "implicit" marker on the operand is wrong, but it doesn't actually break anything.
