Force eager compilation of parenthesized functions.
...
This makes the compiler use eager compilation for function literals that
are parenthesized. We consider this to be a hint that the function will
be called immediatly and hence try to avoid parsing it twice. The parser
already respects this heuristic.

Fixed compound/count operations with getter-only accessor properties.
...
The underlying problem is that for compound/count operations we use the *load*
type feedback for storing, too. For normal properties this doesn't matter, but
for accessor properties we should better use the *store* type feedback, which
would be available, too. This consistent feedback usage could be guaranteed if
we removed the heavy copy-n-paste in the crankshaft code generation for
compound/count operations and assignments/property loads.
To be on the safe side, we postpone this refactoring and do a quick and easily
mergeable fix.

android: refine custom ucontext_t definitions.
...
This is a forward-compatible change to avoid type/naming
conflicts when the Android platform/NDK will update its
<signal.h> header to properly define 'struct sigcontext',
'mcontext_t' and 'ucontext_t'.
In particular:
- Do not define 'struct sigcontext.h' to avoid
conflicts with the C library definition (which
is different, see below).
- Only provide custom ucontext_t declarations if
the Android <signal.h> doesn't provide it. This can
be tested with a macro check (__BIONIC_HAVE_UCONTEXT_T)
+ Use 'gettid()' on Android since it is available (at all
API levels).

shallow traversal of the object graph spanned by one code object, and
breaks at points where application objects are encountered. So it will
not trip on cross-context leaks introduced by the application itself.
