1f7ebddd5f Revert r159528 which taught lit's builtin shell test runner about the
'|&' bash syntax. We have lots of users with a bash on their system
which doesn't support this syntax, and as bash is still significantly
faster, we should support them.

The test suite has already been updated to cope with this.

cab8e1ed55 Teach the built-in shell test runner in lit to handle '|&'-style pipes.
This is directly cloned from the logic in the TCL test bits of lit.
Hopefully will fix most of the windows build bot fallout.

0d9513c74f Make NumMicroOps a variable in the subtarget's instruction itinerary.
The TargetInstrInfo::getNumMicroOps API does not change, but soon it
will be used by MachineScheduler. Now each subtarget can specify the
number of micro-ops per itinerary class. For ARM, this is currently
always dynamic (-1), because it is used for load/store multiple which
depends on the number of register operands.

Zero is now a valid number of micro-ops. This can be used for
nop pseudo-instructions or instructions that the hardware can squash
during dispatch.

ca578e7ba6 Teach TableGen to put chains on more instructions
When generating selection tables for Pat instances, TableGen relied on
an output Instruction's Pattern field being set to infer whether a
chain should be added.

This patch adds additional logic to check various flag fields so that
correct code can be generated even if Pattern is unset.

4dbfdfba6c TableGen: AsmMatcher support for better operand diagnostics.
"Invalid operand" may be a completely correct diagnostic, but it's often
insufficiently specific to really help identify and fix the problem in
assembly source. Allow a target to specify a more-specific diagnostic kind
for each AsmOperandClass derived definition and use that to provide
more detailed diagnostics when an operant of that class resulted in a
match failure.

b460a33829 Revert r158679 - use case is unclear (and it increases the memory footprint).
Original commit message:

    This patch changes the type used to hold the FU bitset from unsigned to uint64_t.
    This will be needed for some upcoming PowerPC itineraries.

"GenericItineraries" would only make sense if it contained real

return the smallest set of missing features from the alternatives as
that's most likely to be the one that's desired.

f52baf72c1 Emit register unit lists for each register.
Register units are already used internally in TableGen to compute
register pressure sets and overlapping registers. This patch makes them
available to the code generators.

The register unit lists are differentially encoded so they can be reused
for many related registers. This keeps the total size of the lists below
200 bytes for most targets. ARM has the largest table at 560 bytes.

Add an MCRegUnitIterator for traversing the register unit lists. It
provides an abstract interface so the representation can be changed in
the future without changing all clients.
