e72e773ad0 remove SkTCast
SkTCast is functionally equivalent to reinterpret_cast.

The comment about SkTCast helping to avoid strict alising issues is not
true.  Dereferencing a pointer cast to a pointer of an unrelated type is
always undefined, even if smuggled through a union like in SkTCast.

To really avoid aliasing issues, you need to make a union[1] of the two
value types, or better, memcpy between values.  I've had to fix
MatrixText.cpp where switching to reinterpret_cast actually let Clang
notice and warn that we're exploiting undefined behavior, and
GrSwizzle.h and SkCamera.cpp caught by GCC.

I've switched SkTLList over to use SkAlignedSTStorage, which seems
to help convince some GCC versions that fObj is used in a sound way.

[1] The union punning trick is non-standard in C++, but GCC and MSVC
both explicitly support it.  I believe Clang does not officially
explicitly support it, but probably does quietly for GCC compatibility.

running bench [640 480] math_sk_float_rsqrt    NONRENDERING: cmsecs =      1.99

Desktop:
running bench [640 480]      math_fastIsqrt    NONRENDERING: cmsecs =      0.89
running bench [640 480]      math_slowIsqrt    NONRENDERING: cmsecs =      0.94
running bench [640 480] math_sk_float_rsqrt    NONRENDERING: cmsecs =      0.09

Haven't found any other benches where this is a significant effect yet.

fcc9ca09a5 by hook or by crook, force gcc to return the value of SkPoint::length() to actually be a float
instead of a double. Otherwise we can't properly test for overflow with large values.

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.
