Henrik Rydgård d243737c11 Revert "Convert the pre-rotation to just the matrix multiplication." 
After the previous commit, the optimization is no longer needed, and
unnecessarily bloats the uniform buffer.

This reverts commit 62bcb1785e809649ba88b49e24c5217f457fa040.

Henrik Rydgård 28166cb35d Add "allocation slack" to our pushbuffers. Fixes a memory overwrite bug 
Reported by Joseph on Discord.

Sometimes, things could align perfectly so allocations happend exactly
at the end of a pushbuffer. At the same time, we allow our vertex decoder to write an extra few
bytes if it needs to for speed. Unfortunately I missed this interaction,
resulting in some uncommon crashes that were especially common with
heavy-geometry things like modified GTA LCS with PS2 assets, for
example.

The problem was reported with Vulkan, but our OpenGL backend had the
same issue too.

Chris Healyandcphealy 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 Healyandcphealy 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%)

fcrwrandHenrik Rydgård 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.
