9a5ec9c57c Fix platform unittests. 
Follow-up to 87db4ff1f4, which added
suppressions to unittests.status and a special case for Android to the
ThreadLocalStorageTest, both of which are unneccessary and should be
handled differently for the GTest based unittests.

87db4ff1f4 Fix/suppress unittests broken on Android 
cctest/test-threads/ThreadJoinSelf is suppressed for Android, but the
test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.

unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).

cctest/test-mark-compact/RegressJoinThreadsOnIsolateDeinit can't deal
with shared mappings. Check for 's' instead of '-'.

009fe698ee The file snapshot_blob_host.bin was supposed to be generated when building the host toolset. However, the file snapshot_blob.bin was being generated instead, under every set of conditions. 
Because of this, every time we build the host toolset, snapshot_blob_host.bin is not found. This causes the target (v8_external_snapshot) that generates such file to be run. This target generates snapshot_blob.bin instead of snapshot_blob_host.bin. This in turn causes all the targets that depend on snapshot_blob.bin to run again.

After this, we still don't have snapshot_blob_host.bin. So the next time we build, the whole process described above happens again.

3d58b82add Fix for 435073: CHECK failure in CHECK(p->IsSmi()) failed. 
The bug was an error when copying arrays in crankshaft. If it's a holey smi
array, the copy must be done as FAST_HOLEY_ELEMENTS to prevent representation
changes from being inserted that deopt on encountering the hole.

Also, prevent inlining array pop() and shift() if the length is read-only.
