Extend profman to generate profiles with inline caches

Extend profman logic to generate profiles based on a simple textual
respresentation. This will help writing tests for profile guided
compilation.

Before this CL, profman was able to generate profiles based on a list of
classes like:
java.lang.Comparable
java.lang.Math
java.lang.Object

This CL, enables profman to understand methods and classes alike. The
new format is:

# Classes
Ljava/lang/Comparable;
Ljava/lang/Math;
# Methods with inline caches
LTestInline;->inlinePolymorhic(LSuper;)I+LSubA;,LSubB;,LSubC;
LTestInline;->noInlineCache(LSuper;)I

"LTestInline;->inlinePolymorhic(LSuper;)I+LSubA;,LSubB;,LSubC;"
means that method `int inlineMonomorphicSubA(Super)` from class Main
will be added to the profile with the inline cache (SubA,SubB) for its
one and only invoke virtual.

@Main#noInlineCache:(LSuper;)I+;
meaning that method `int noInlineCache' from class Main will be added
to the profile with no inline cache.

Note that the methods are allowed to have a single invoke virtual in
their dex bytecode. That is to keep the parsing the file format
simple and easy to use.

Also, add a few more tests for profiles and fix an issue caused by
writing the dex files in a possibly wrong order.
