Chris Healy 6dae3327a6 GPU: Remove dead helper functions from fragment shader 
Remove two unused helper functions that were left behind after refactoring:

1. unpackUVec3: Left over from commit 4329aaa31c ("GPU: Apply color
   test mask as a uint") which refactored color test to use
   roundAndScaleTo8x4 with direct uint comparison instead of unpacking
   to uvec3 components.

2. packFloatsTo8x4: Left over from commit aec22491fe ("Don't expand
   alphaColorRef to 128 bytes") which changed u_alphacolorref from vec4
   to uint, making the float-to-uint packing function unnecessary.

Both functions were defined but never called, wasting shader compilation
time and binary size for shaders that enable color testing.

Chris Healy 9ed5dcdc27 GPU: Use inversesqrt for light distance and half-vector calculations 
Replace length()/normalize() with inversesqrt() pattern for better
performance on mobile GPUs. The inversesqrt instruction is a single
hardware operation, while length() requires sqrt(dot()) and normalize()
requires inversesqrt internally plus a multiply.

Changes:
1. Light distance calculation:
   Before: distance = length(toLight); toLight /= distance;
   After:  distSq = dot(toLight, toLight);
           invDist = inversesqrt(distSq);
           distance = distSq * invDist;
           toLight *= invDist;

2. Specular half-vector normalization:
   Before: ldot = dot(normalize(toLight + vec3(0,0,1)), worldnormal);
   After:  halfVec = toLight + vec3(0,0,1);
           halfInvLen = inversesqrt(dot(halfVec, halfVec));
           ldot = dot(halfVec, worldnormal) * halfInvLen;

Also reuses distSq in attenuation calculation to avoid recomputing
distance*distance.

Offline shader compiler results (vertex shader with 4-light ubershader):

Mali (malioc):
  G31 (Bifrost): 44.90 -> 40.50 cycles (-9.8%)
  G52 (Bifrost): 14.97 -> 13.50 cycles (-9.8%)
  G310 (Valhall): 13.88 -> 12.88 cycles (-7.2%)
  G57 (Valhall):  7.60 ->  6.97 cycles (-8.3%)

PowerVR (Profiling Compilers):
  Series 8 GE8300: 322 -> 302 ALU cycles (-6.2%)
  Series 9 GM9445: 296 -> 280 ALU cycles (-5.4%)
  Series B BXM:    560 -> 540 instructions (-3.6%)

fcrwr cc4bf75717 Fix block transfer clipping 
Fix block transfer clipping that happened due to code not taking block
transfer offsets into account when finding framebuffers for block
transfer and when creating ram framebuffer.

fcrwr f3c98442d5 Apply changes by fcrwr, fixing (mostly) shadows in Silent Hill: Shattered Memories 
The game actually implements proper shadow mapping using some wicked
trickery, including framebuffer color reinterpretation. This finally
gets it working, by filling in some gaps in the existing mechanisms.

Unfortunately there's some precision issue that needs to be looked at,
as it can currently look quite stripy, very typical of shadow mapping.
