The pointer entry 'temps' always refers to the array entry 'static_temps'.
Removing the pointer and renaming 'static_temps' to 'temps' reduces the
size of TCGContext (4 or 8 byte) and allows better code generation.

The size of the executables is typically reduced by about 80 byte.
Usually smaller code also runs faster, but that effect will be
very small here.
