Jit64: Don't flush the regcache on bcx
Support conditional register cache flushing on ARMv7.
Similar to PR #451, but for ARM as well.
Change register cache to using an enum to determine flush mode.
This is easier to identify what the flush is doing rather than a "true" as argument.
Add conditional register cache flushing to JIT64's bcctrx conditional route.
Add conditional register cache flushing to JIT64's bcx instruction.
Add conditional register cache flushing to JIT64's twx instruction.
Fix a few code style remarks.
Removes some casting of size_t to int.
