MVE adds the lsll, lsrl and asrl instructions, which perform a shift on a 64 bit value separated into two 32 bit registers.
The Expand64BitShift function is modified to accept ISD::SHL, ISD::SRL and ISD::SRA and convert it into the appropriate opcode in ARMISD. An SHL is converted into an lsll, an SRL is converted into an lsrl for the immediate form and a negation and lsll for the register form, and SRA is converted into an asrl.
test/CodeGen/ARM/shift_parts.ll is added to test the logic of emitting these instructions.

[InlineCost] make InlineCost assignable
Summary:
Current InlineCost is not assignable because of const members Cost and Threshold.
I dont see practical benefits from having them const (access to these members is
private and internal interactions are rather simple). On other hand that makes
it hard to use as a member in some other data structure where assignability is necessary.
I'm going to use InlineCost in a downstream inliner that maintains a complex queue
of candidate call-sites and thus keeping and recalculating InlineCost is necessary.
This patch just removes 'const' from both members, making InlineCost assignable.

[CodeGen] [SelectionDAG] More efficient code for X % C == 0 (UREM case) (try 3)
Summary:
I'm submitting a new revision since i don't understand how to reclaim/reopen/take over the existing one, D50222.
There is no such action in "Add Action" menu...
This implements an optimization described in Hacker's Delight 10-17: when `C` is constant,
the result of `X % C == 0` can be computed more cheaply without actually calculating the remainder.
The motivation is discussed here: https://bugs.llvm.org/show_bug.cgi?id=35479.
This is a recommit, the original commit rL364563 was reverted in rL364568
because test-suite detected miscompile - the new comparison constant 'Q'
was being computed incorrectly (we divided by `D0` instead of `D`).
Original patch D50222 by @hermord (Dmytro Shynkevych)
Notes:
- In principle, it's possible to also handle the `X % C1 == C2` case, as discussed on bugzilla.
This seems to require an extra branch on overflow, so I refrained from implementing this for now.
- An explicit check for when the `REM` can be reduced to just its LHS is included:
the `X % C` == 0 optimization breaks `test1` in `test/CodeGen/X86/jump_sign.ll` otherwise.
I hadn't managed to find a better way to not generate worse output in this case.
- The `test/CodeGen/X86/jump_sign.ll` regresses, and is being fixed by a followup patch D63390.

Use getConstantOperandAPInt instead of getConstantOperandVal for comparisons.
getConstantOperandAPInt avoids any large integer issues - these are unlikely but the fuzzers do like to mess around.....

[CodeGen] [SelectionDAG] More efficient code for X % C == 0 (UREM case) (try 2)
Summary:
I'm submitting a new revision since i don't understand how to reclaim/reopen/take over the existing one, D50222.
There is no such action in "Add Action" menu...
Original patch D50222 by @hermord (Dmytro Shynkevych)
This implements an optimization described in Hacker's Delight 10-17: when `C` is constant,
the result of `X % C == 0` can be computed more cheaply without actually calculating the remainder.
The motivation is discussed here: https://bugs.llvm.org/show_bug.cgi?id=35479.
Original patch author: @hermord (Dmytro Shynkevych)!
Notes:
- In principle, it's possible to also handle the `X % C1 == C2` case, as discussed on bugzilla.
This seems to require an extra branch on overflow, so I refrained from implementing this for now.
- An explicit check for when the `REM` can be reduced to just its LHS is included:
the `X % C` == 0 optimization breaks `test1` in `test/CodeGen/X86/jump_sign.ll` otherwise.
I hadn't managed to find a better way to not generate worse output in this case.
- The `test/CodeGen/X86/jump_sign.ll` regresses, and is being fixed by a followup patch D63390.

[Attr] Add "willreturn" function attribute
This patch introduces a new function attribute, willreturn, to indicate
that a call of this function will either exhibit undefined behavior or
comes back and continues execution at a point in the existing call stack
that includes the current invocation.
This attribute guarantees that the function does not have any endless
loops, endless recursion, or terminating functions like abort or exit.

Bitcode: derive all types used from records instead of Values.
There is existing bitcode that we need to support where the structured nature
of pointer types is used to derive the result type of some operation. For
example a GEP's operation and result will be based on its input Type.
When pointers become opaque, the BitcodeReader will still have access to this
information because it's explicitly told how to construct the more complex
types used, but this information will not be attached to any Value that gets
looked up. This changes BitcodeReader so that in all places which use type
information in this manner, it's derived from a side-table rather than from the
Value in question.
