[ARM] Align blocks that are not fallthough targets

If the previous block in a function does not fallthough, adding nop's to
align it will never be executed. This means we can freely (except for
codesize) align more branches. This happens in constantislandspass (as
it cannot happen later) and only happens at aggressive optimization
levels as it does increase codesize.

[llvm][AArch64] Simplify (and (sign_extend..) #bitmask).

Fold

VT = (and (sign_extend NarrowVT to VT) #bitmask)

into

VT = (zero_extend NarrowVT)

With this combine, the test replaces a sign extended load + an
unsigned extention with a zero extended load to render one of the
operands of the last multiplication.

[ARM] Cortex-M4 schedule additions

This is an attempt to fill in some of the missing instructions from the
Cortex-M4 schedule, and make it easier to do the same for other ARM cpus.

- Some instructions are marked as hasNoSchedulingInfo as they are pseudos or
otherwise do not require scheduling info
- A lot of features have been marked not supported
- Some WriteRes's have been added for cvt instructions.
- Some extra instruction latencies have been added, notably by relaxing the
regex for dsp instruction to catch more cases, and some fp instructions.

This goes a long way to get the CompleteModel working for this CPU. It does not
go far enough as to get all scheduling info for all output operands correct.

[ARM] Cortex-M4 schedule

This patch adds a simple Cortex-M4 schedule, renaming the existing M3
schedule to M4 and filling in the latencies as-per the Cortex-M4 TRM:
https://developer.arm.com/docs/ddi0439/latest

Most of these are 1, with the important exception being loads taking 2
cycles. A few others are also higher, but I don't believe they make a
large difference. I've repurposed the M3 schedule as the latencies are
mostly the same between the two cores, with the M4 having more FP and
DSP instructions. We also turn on MISched and UseAA for the cores that
now use this.

It also adds some schedule Write's to various instruction to make things
simpler.

[ARM][ParallelDSP] Enable multiple uses of loads

When choosing whether a pair of loads can be combined into a single
wide load, we check that the load only has a sext user and that sext
also only has one user. But this can prevent the transformation in
the cases when parallel macs use the same loaded data multiple times.

To enable this, we need to fix up any other uses after creating the
wide load: generating a trunc and a shift + trunc pair to recreate
the narrow values. We also need to keep a record of which loads have
already been widened.
