3116dce338 Rename the narrow shift right immediate operands to "shr_imm*" operands. Also
expand the testing of the narrowing shift right instructions.

No functionality change.

b3fcc06d21 In Thumb1 mode the constant might be materialized via the load from constpool. Emit unwinding information in case when this load from constpool is used to change the stack pointer in the prologue.

3daccd82d3 Implement frame unwinding information emission for Thumb1. Not finished yet because there is no way given the constpool index to examine the actual entry: the reason is clones inserted by constant island pass, which are not tracked at all! The only connection is done during asmprinting time via magic label names which is really gross and needs to be eventually fixed.

e0ef509aeb Increased the register pressure limit on x86_64 from 8 to 12
regs. This is the only change in this checkin that may affects the
default scheduler. With better register tracking and heuristics, it
doesn't make sense to artificially lower the register limit so much.

Added -sched-high-latency-cycles and X86InstrInfo::isHighLatencyDef to
give the scheduler a way to account for div and sqrt on targets that
don't have an itinerary. It is currently defaults to 10 (the actual
number doesn't matter much), but only takes effect on non-default
schedulers: list-hybrid and list-ilp.

Added several heuristics that can be individually disabled for the
non-default sched=list-ilp mode. This helps us determine how much
better we can do on a given benchmark than the default
scheduler. Certain compute intensive loops run much faster in this
mode with the right set of heuristics, and it doesn't seem to have
much negative impact elsewhere. Not all of the heuristics are needed,
but we still need to experiment to decide which should be disabled by
default for sched=list-ilp.

31cbac1cfe Allow vector shifts (shl,lshr,ashr) on SPU.
There was a previous implementation with patterns that would 
have matched e.g. 
	shl <v4i32> <i32>,
but this is not valid LLVM IR so they never were selected.
