Always support debugging and profiling.
This eliminates the use of the WITH_DEBUGGER and WITH_PROFILER
conditional compilation flags. We've never shipped a device without
these features, and it's unlikely we ever will. They're not worth
the code clutter they cause.
As usual, since I can't test the x86-atom code I left that alone and
added an item to the TODO list.
Bug 2923442.

Add native method arguments to GC scan.
We want to identify arguments passed to native methods (internal native
or JNI) so that we can tell the GC to leave those blocks alone. The
alternative is to add explicit "add to tracked ref list" calls to a
bunch of internal natives and to the JNI call bridge.
We walk through the shorty signature to make this a precise scan.
Since something is now looking at the method arguments, it was necessary
to actually set a value in the argument area on the stack for the "fake"
native method entry points used for the main thread and for externally-
created threads that are later attached to the VM.
(The implementation is currently #ifdefed-out, since there's nothing
for it to do yet.)

Fix supplementary character support.
Fixes all known bugs in our handling of supplementary characters. This change
introduces a performance regression on the assumption that it won't be released
without a corresponding JIT change to enable the code to be inlined back to
pretty much what it used to be.

An InlineNative for String.isEmpty, so it's not slower than length() == 0.
Before:
benchmark ns logarithmic runtime
IsEmpty 115 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
LengthEqualsZero 21 XXXXX||||||||||||||
With C intrinsic:
IsEmpty 30 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
LengthEqualsZero 20 XXXXXXXXXXXXXXXXXXXX||||||
With assembler intrinsic:
IsEmpty 15 XXXXXXXXXXXXXXXXXXXX||||||
LengthEqualsZero 21 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
(All times on passion.)

Add inline version of String.indexOf().
This provides an inline-native version of String.indexOf(int) and
String.indexOf(int, int), i.e. the functions that work like strchr().
Has a fairly solid impact on specific benchmarks. Might give a boost to
an app somewhere.
Added some indexOf tests to 020-string.
Added hard-coded field offsets for String. These are verified during
startup. Improves some of our String micro-benchmarks by ~10%.

Inline some java.lang.Math functions.
For a first pass, I inlined the various flavors of abs(), min()/max() on
integers, sqrt(), cos(), and sin(). These were selected based on a
static analysis of a few of our jar files.
A test of repeated sin/cos/sqrt calls on a G1-class device showed an
improvement of 28%. This would improve more on devices with VFP
support if the VM is compiled with -mfpu=vfp.
Also: clarified a warning and removed some "#if 0" stuff.
