Fix a case where a reg is spilled before being freed, leading to an assert

In genRangeCheck(), under stress, the call to the range check helper
might spill the index register. This leads to an assert in rsMarkRegFree():
`rsIsTreeInReg(reg, tree)`. So, instead of calling rsMarkRegFree,
call genReleaseReg(), which handles this case.

This unfortunately reloads the spilled tree, which seems unnecessary, but it
otherwise frees the register fine.

One subtlety that is not obvious to me: the current code calls
`rsMarkRegFree(node->gtRegNum, node)` but `genRangeCheck()`
calls `rsMarkRegFree(genRegMask(node->gtRegNum))`. I'm not 100% sure
these are equivalent.

Fix ARM32 spill temp allocation

For ARM32 only, lvaAssignVirtualFrameOffsetsToLocals() forced temps
to be allocated high in the frame, with the comment:

```
// On ARM, SP based offsets use smaller encoding. Since temps are relatively
// rarer than lcl usage, allocate them farther from SP.
```

However, lvaFrameAddress(), when estimating the maximum frame offset for a
temp before final frame layout, did not consider this: it always assumed
temps were low on the frame. In addition, lvaTempsHaveLargerOffsetThanVars()
always returns `false` for ARM.

This caused an asserts with JitStress when we had an SP frame with large
locals, and estimated a small offset to a TEMP before final frame layout
but required a very large offset after final frame layout -- an offset that
could not be encoded by the chosen instruction. (These very large non-FP
frames might also exist only because of stress, such as GS stress.)

To fix this, simply remove the optimization, for both RyuJIT and LEGACY_BACKEND.

There is a very small code size regression (242 bytes over 42M) in asm diffs on internal

Fix errors in MSBuild prperties initialization in System.Private.CoreLib.csproj (#12356)

Fixes issue #12355

Project System.Private.CoreLib.csproj imports directly Microsoft.Net.Compilers.props
at line# 4 before including dir.props from repo root. $(RepoRoot)/dir.props imports
Microsoft.Net.Compilers.props at line# 186. As a result of this sequence of duplicated
project imports and lack of safeguards against importing the same .props file twice
MSBuild reports that Microsoft.Net.Compilers.props file is included twice with warning
that second import will be ignored - in this case not evaluated. This results
in initialization of Microsoft.Net.Compilers.props values to defaults because MSBuild
evaluates Microsoft.Net.Compilers.props only once before $(RepoRoot)/dir.props are included.
Removing import of Microsoft.Net.Compilers.props from System.Private.CoreLib.csproj
and moving $(RepoRoot)/dir.props file import to top of System.Private.CoreLib.csproj
solves these problems by ensuring expected order of evaluation of Microsoft.Net.Compilers.props
file by MSBuild after all project wide values are initialized in $(RepoRoot)/dir.props.

Stephen Toub [Mon, 10 Jul 2017 01:52:29 +0000 (21:52 -0400)]
Improve the performance of CancellationToken.Register / CancellationTokenRegistration.Dispose

CancellationToken.Register currently allocates an object per call.  This PR makes it allocation-free (amortized).

The current implementation was optimized for scalability, using a lock-free algorithm to minimize contention when lots of threads are registering with a token concurrently.  Each registration allocates an object which is then stored into a lock-free sparse array data structure.  But the level of scalability enabled is unnecessary for the vast majority of CancellationToken usage, adds non-trivial complexity to the implementation, and adds costs to the most common usage scenarios, e.g. a single CancellationToken that registered with and the unregistered with repeatedly.

The new implementation strikes a (IMO) better balance between performance and scalability, retaining most of the latter while doing much better for the former in the most interesting use cases.  CancellationTokenSource now maintains an array of partition objects, each of which is lazily-initialized, contains a lock that protects that partition, and contains a linked list of registration objects.  The striped locking helps maintain most of the scalability and also enables node reuse due to not suffering from ABA problems.

(All numbers that follow are 64-bit.)

The size of CancellationTokenSource itself doesn't change (64 bytes), so allocating a CancellationTokenSource and then never registering with its token remains the same in both speed and space.

The size overhead associated with the first registration on a CancellationTokenSource improves.  With the old implementation, the first registration would result in 272 bytes allocated, whereas with the new implementation that shrinks to 218.

Each additional registration at the same time in the CancellationToken is now larger than in the old implementation, 80 bytes instead of ~56 bytes (it varies in the old implementation due to the details of the lock-free algorithm and when new segments are created), but these new node allocations are reusable.  So if you register 100 registrations with the same CancellationToken and don't unregister any of them, you'll incur ~8000 bytes of allocation instead of ~5600, but if you instead register and unregister them 100 times, you'll only incur ~80 bytes of allocation instead of ~5600, with objects reused for the former case but not the latter case.

Speed is also significantly improved.  A single thread registering and unregistering repeatedly from a token is now ~2x the old implementation in throughput.  Similarly with eight threads on eight logical cores all registering/unregistering concurrently.

Finally, the size of CancellationTokenRegistration also shrinks.  This struct is often contained in other classes that have registered with the token, and so will end up shrinking the size of those allocations as well.
