tcg/optimize: Adjust TempOptInfo allocation

Do not allocate a large block for indexing. Instead, allocate
for each temporary as they are seen.

In general, this will use less memory, if we consider that most
TBs do not touch every target register. This also allows us to
allocate TempOptInfo for new temps created during optimization.

tcg/optimize: Add fallthrough annotations

To be able to compile this file with -Werror=implicit-fallthrough,
we need to add some fallthrough annotations to the case statements
that might fall through. Unfortunately, the typical "/* fallthrough */"
comments do not work here as expected since some case labels are
wrapped in macros and the compiler fails to match the comments in
this case. But using __attribute__((fallthrough)) seems to work fine,
so let's use that instead (by introducing a new QEMU_FALLTHROUGH
macro in our compiler.h header file).
