This patch implemented TTI.IntImmCost() properly. Each BPF insn has 32bit immediate space, so for any immediate which can be represented as 32bit signed int, the cost is technically free. If an int cannot be presented as a 32bit signed int, a ld_imm64 instruction is needed and a TCC_Basic is returned. This change is motivated when we observed that several bpf selftests failed with latest llvm trunk, e.g., #10/16 strobemeta.o:FAIL #10/17 strobemeta_nounroll1.o:FAIL #10/18 strobemeta_nounroll2.o:FAIL #10/19 strobemeta_subprogs.o:FAIL #96 snprintf_btf:FAIL The reason of the failure is due to that SpeculateAroundPHIsPass did aggressive transformation which alters control flow for which currently verifer cannot handle well. In llvm12, SpeculateAroundPHIsPass is not called. SpeculateAroundPHIsPass relied on TTI.getIntImmCost() and TTI.getIntImmCostInst() for profitability analysis. This patch implemented TTI.getIntImmCost() properly for BPF backend which also prevented transformation which caused the above test failures. Differential Revision: https://reviews.llvm.org/D96448

We experienced some deadlocks when we used multiple threads for logging using `scan-builds` intercept-build tool when we used multiple threads by e.g. logging `make -j16` ``` (gdb) bt #0 0x00007f2bb3aff110 in __lll_lock_wait () from /lib/x86_64-linux-gnu/libpthread.so.0 plctlab#1 0x00007f2bb3af70a3 in pthread_mutex_lock () from /lib/x86_64-linux-gnu/libpthread.so.0 plctlab#2 0x00007f2bb3d152e4 in ??

() ``` I think the gcc's exit call caused the injected `libear.so` to be unloaded by the `ld`, which in turn called the `void on_unload() __attribute__((destructor))`. That tried to acquire an already locked mutex which was left locked in the `bear_report_call()` call, that probably encountered some error and returned early when it forgot to unlock the mutex. All of these are speculation since from the backtrace I could not verify if frames 2 and 3 are in fact corresponding to the `libear.so` module. But I think it's a fairly safe bet. So, hereby I'm releasing the held mutex on *all paths*, even if some failure happens. PS: I would use lock_guards, but it's C.
