compiler: never omit assertions if using a static analysis tool
Assertions help both Coverity and the clang static analyzer avoid false positives, but on the other hand both are confused when the condition is compiled as (void)(x != FOO). Always expand assertion macros when using Coverity or clang, through a new QEMU_STATIC_ANALYSIS preprocessor symbol. This fixes a couple false positives in TCG.
