`void print_ints_uchar(param_t *p, const void *vals , int n, int is_unsigned)`
The second argument is a void pointer, but when we call this function with a non-void
pointer, in traditional C code, this action is legal, but when this pointer carrys different
address space, llvm will report error, we now just avoid this check
`print_ints_uchar(&p, &val, vector_length, is_unsigned)`
In our previous design, the libclc library is built into static library which make the generated
ELF file having a large size, now we change compiler and linker option to make generated ELF file size much smaller, detail information can be seen in this pull request https://github.com/THU-DSP-LAB/pocl/pull/11
In our previous calling convention design, all non-kernel arguments are passed
by VGPRS or TP stack, but when the arguments point to private memory address
space, the wrong memory access instructions will be generated, because private
memory based address is scalar register
Because ventus riscv is designed specially for OpenCL language, we originally add or remove some language features mainly for serving OpenCL, but we now need to add customized `printf` function which is expected to be written in C, so we need also to add support for C language features in current ventus

This patch adds forward declarations of raw_ostream to those header
files that are relying on the forward declaration of raw_ostream in
llvm/include/llvm/ADT/Optional.h.
I'm planning to move operator<< for Optional<T> and std::optional<T>
from Optional.h to llvm/include/llvm/Support/raw_ostream.h. Once I do
so, we no longer need to forward-declare raw_ostream in Optional.h.
D130887 uses a dummy empty section `sanmd_covered` (with the SHF_GNU_RETAIN flag on
ELF) to prevent `undefined symbol: __start_sanmd_covered` if all `sanmd_covered`
are discarded by `ld --gc-sections` (in `-z start-stop-gc` mode).
The dummy `sanmd_covered` does not have the SHF_LINK_ORDER flag, so mixing it
with SHF_LINK_ORDER `sanmd_covered` causes an issue to GNU ld<2.36
(https://sourceware.org/bugzilla/show_bug.cgi?id=26256).
Similar to D98903 for SanitizerCoverage, let's make encapsulation symbols
undefined weak[1]. This additionally avoids size cost due to the dummy section and
symbol.

This includes TT_MacroBlockBegin and TT_MacroBlockEnd as well.
We can no longer use MatchingParen of FormatToken as an indicator
to mark optional braces. Instead, we directly set Optional of an
l_brace first and reset it later if it turns out that the braces
are not optional.
Also added a test case for deeply nested loops.
