JBR-4017 Open com.jetbrains.bootstrap package only for reflection

Make C1 hotspot compiler bail out during CFG construction if there's a
cycle in the graph that isn't a natural loop and that has led to an
unexpected state of stack/locals like missing a phi function.

This is a temporary measure that lets hotspot continue working
even after encountering such bytecode patterns. The full solution
will probably involve more sophisticated CFG checks.

This means that whenever you add or update a package in Cygwin, you might (inadvertently) update tools that are used by the JDK build process, and that can cause unexpected build problems.</p>

 <p>Verify that the summary at the end looks correct. Are you indeed using the Boot JDK and native toolchain that you expect?</p>
 <p>By default, the JDK has a strict approach where warnings from the compiler is considered errors which fail the build. For very new or very old compiler versions, this can trigger new classes of warnings, which thus fails the build. Run <code>configure</code> with <code>--disable-warnings-as-errors</code> to turn of this behavior. (The warnings will still show, but not make the build fail.)</p>

 ## Hints and Suggestions for Advanced Users
 
-### Setting Up a Forest for Pushing Changes (defpath)
-
-To help you prepare a proper push path for a Mercurial repository, there exists
-a useful tool known as [defpath](
-http://openjdk.java.net/projects/code-tools/defpath). It will help you setup a
-proper push path for pushing changes to the JDK.
-
-Install the extension by cloning
-`http://hg.openjdk.java.net/code-tools/defpath` and updating your `.hgrc` file.
-Here's one way to do this:
-
-```
-cd ~
-mkdir hg-ext
-cd hg-ext
-hg clone http://hg.openjdk.java.net/code-tools/defpath
-cat << EOT >> ~/.hgrc
-[extensions]
-defpath=~/hg-ext/defpath/defpath.py
-EOT
-```
-
-You can now setup a proper push path using:
-```
-hg defpath -d -u <your OpenJDK username>
-```
-
-If you also have the `trees` extension installed in Mercurial, you will
-automatically get a `tdefpath` command, which is even more useful. By running
-`hg tdefpath -du <username>` in the top repository of your forest, all repos
-will get setup automatically. This is the recommended usage.

+Subject: [PATCH 29/33] JBR-3867 - update keys of jvmti TAG map after
+ redefinition
+
+jdwp keeps relation class_ptr->class_ref in jvmti tag. class_ptr is used
+as a tag key, tag value is refnode. There are new class_ptrs after
+redefinition, therefore jdwp redefinition method update all affected
+keys in the tag map.

+Subject: [PATCH 32/33] JBR-3937 Fix crashes in C1/C2 compilers
+
+There is a race condition in enhanced redefinition with C1/C2. Therefore
+the patch stops C1/C2 compilation before redefinition and release after
+redefinition finishing. There is no performance impact since dcevm
+flushes all code cache.
