7a3eeacd87 Make SkMatrix44::invert() check for finite 1/det instead of magic value 
Previously we were checking to see if the magnitude of determinant of the 
matrix to be inverted was less than 1.0e-8, which is a magic number possibly
plucked from Graphics Gems. After some discussion, it's been determined (ha)
that we can simply check to see if 1/det is finite and if so proceed.

57a54e33cf Add SkMatrix44 constructor that allows user to control the initialization 
method.  Preliminary results using Chromium's cc_perftests
show that we can avoid almost half of the default constructors from
redundantly/unnecessarily initializing the matrix to identity.

7d68335eb4 add getTypes() to SkMatrix44, to cache how complex the matrix is. 
add bench

optimize operator== by performing 4 compares in a row before checking
optimize setconcat by noting when we can write the answer directly into this

At least on this macbook, I had to mark helpers like isIdentity() as inline to get them inlined.

f11cf9ff88 Add SkMatrix44::setColMajord, etc. 
We have accessors for efficiently getting the matirx data, and it would be nice
if we had similar methods for setting the matrix entries.

easier, so I've included that in this cl as well.

42639cddc3 fix warnings on Mac in tests 
Fix these class of warnings:
- unused functions
- unused locals
- sign mismatch
- missing function prototypes
- missing newline at end of file
- 64 to 32 bit truncation

The changes prefer to link in dead code in the debug build
with 'if (false)' than to comment it out, but trivial cases
are commented out or sometimes deleted if it appears to be
a copy/paste error.
