Port from tfs: onload exception debugger crash fix (dotnet/coreclr#4868)

The ExceptionHijackPersonalityRoutine was retrieving a context from a
particular stack frame, but the calling conventions for the function
executing in that frame allow it to overwrite the context. This was
causing the debugger to crash for exceptions thrown from the onload
method in winforms on x64.

The fix is to instead retrieve the context from the previous stack
frame, whose layout is set up explicitly in ExceptionHijack.

Fix to Jit32 test b46659.exe  failure.

Here is the git hub issue: https://github.com/dotnet/coreclr/issues/4547

The repro case is

     i = -111
     while ( i > 0)
     {
         // another nested loop goes here
     }
     return 100

     After assertionProp, due to while loop condition lot of blocks/stmts get deleted as unreachable but optLoopCount is never decremented.  Later when optLoopCodeMotion() gets called, it iterates through optLoopTable[] and tries to access head

     if  ((loopRmv & loopBit)     ||
            tail == 0               ||
            head->bbTreeList == 0    )

     Since entire method reduces to a single basic block, head will be nullptr and accessing head->bbTreeList is leading to an AV.

     Fix: As a safe fix for RTM, also check whether head is nullptr.

Porting the changes to support generic dictionaries lookups in R2R images to the JIT32 implementation, to support the x86 architecture.

All of the changes in importer.cpp were ported from JIT\importer.cpp, which was merged to the coreclr master branch last Friday evening (reviewed and signed-off in a PR on GitHub).

The remaining changes include:
         1) Adjusting #ifdefs to enable the x86 scenario
         2) Implementation of the R2R stub for generic dictionary lookups
         3) Small change in prestub.cpp required for x86 to work correctly

Move NATIVE_DLL_SEARCH_DIRECTORIES probing earlier right before we probe for absolute path and assembly path. This is needed to make sure servicing directories (set in NATIVE_DLL_SEARCH_DIRECTORIES by host) are honored correctly before everything else, along with rest of the NATIVE_DLL_SEARCH_DIRECTORIES probing path. In order to preserve compat with UWP host, I kept the rest of the interop probing logic even when NATIVE_DLL_SEARCH_DIRECTORIES probing path is specified.
To my horror I discovered the fact that we actually never set hmod when loading DLL from NATIVE_DLL_SEARCH_DIRECTORIES probing, and the probably the only saving grace is that our ultimate fallback LoadLibrary call after that would "just work" and return the HMODULE we just loaded... This is now fixed.

Linux/ARM: Change default clang version from 3.5 to 3.6 (dotnet/coreclr#4928)

In case of the cross compilation on the ubuntu 14.04 x64
for Linux/ARM, the default version of clang/llvm that is
generated by "#> sudo ./cross/build-rootfs.sh arm" command
is 3.6 without 3.5 as following:

u14.04@x64> ls ./coreclr/cross/rootfs/arm/usr/lib/clang/3.6
include  lib
u14.04@x64> ls ./coreclr/cross/rootfs/arm/usr/lib/llvm-3.6/
bin  build  include  lib  share

Let's keep the clang/llvm version consistently by moving
the default version from 'clang3.5' to 'clang3.6' at build-time
for Linux/ARM.

These functions have been obviated by a more clearly-defined JIT
startup and shutdown interface.

This fixes a crash in coreclr.dll during DLL unload: the runtime was
calling jitOnDllProcessDetach (which calls jitShutdown) without having
called jitStartup to initialized the JIT.

runtest.sh/cmd currently downloads the coredistools package if COMPlus_GCStress variable is set by TestEnv or test-env options. This is a bit complicated and this doesn't work with a new option for GC stress testing in build/buildtest.cmd. This changeset moves downloading the coredistools package to buildtest.cmd where it takes gcstress option and downloads other packages.

Commit migrated from https://github.com/dotnet/coreclr/commit/ac9360d0569c498e4032c49462dd064b699fe185

Fix CircleInConvex to check result within 1 ULP

This test was checking for the result to be within epsilon of the
expected result, but this is not correct unless the algorithm is
evaluating all interim results to a larger precision.
It would also be more reasonable for the test to compute the expected
result (e.g. using an alternate algorithm), and it would also be nice
to have a method to compute ULP for a given value, but those are beyond
the scope of this fix.
Re-enable the test except for RyuJIT/x86.
