The PICA200 semantics for multiplication are so that when multiplying
inf by exactly 0.0, the result is 0.0, instead of NaN, as defined by
IEEE. This is relied upon by games.

Fixes #1024 (missing OoT interface items)

Shader: RCP and RSQ computes only the 1st component

Shader: Implement DPH and DPHI in interpreter/JIT

emitter: Remove pointer casts

Kernel: Correct(er) handling of Heap and Linear Heap allocations

Tests revealed that the component with w=1 is
SRC1 and not SRC2, it is now fixed on 3dbrew.

This should also technically silence quite a few ubsan warnings.

emitter: Minor cleanup

Functions implemented in a class definition are already implicitly inline.

Fix building under MinGW

Shader: Implement SGE, SGEI and SLT in interpreter/JIT

Improvements for MRU

avoid duplicates
always put the last file loaded to top of the list

GPU: Implement TextureCopy-mode display transfers

Shader: Save caller-saved registers in JIT before a CALL

Shader: Implement EX2 and LG2 in interpreter/JIT

Add coding style about includes

videocore: Added RG8 texture support

Update boost external to v1.59.0
