This fixes the following compiler warnings with clang
tools/genperf/perfect.c:65:6: warning: a function definition without a prototype
is deprecated in all versions of C and is not supported in C2x [-Wdeprecated-non-prototype]
frontends/yasm/yasm.c:1379:23: warning: a function declaration without a prototype

- Create a dummy .llvmasm section for bitcode
- Add [buildversion] directive for setting minos and sdk versions, e.g. [buildversion minos="10.14" sdk="10.14"]. This defaults to 10.5 on x64 and 10.4 on x86.
It appears that GNU binutils always interpret PE/COFF object files as if
they were executable files, namely that the paddr field is a rounded-up
section size (aka virtual size). Yasm previously followed the Microsoft
specification which stated that for object files this field should be set
to the "physical address" of the section (e.g. the sum of all previous
section sizes). However, several other sources state this field should be
set to 0 in object files, and it appears that Microsoft tools accept this.
For compatibility with the GNU tools, this commit makes Yasm always set the
paddr/vsize field to 0.
This commit also eliminates the COFF_SET_VMA customization for COFF
files. Previously this was used to set LMA=VMA in COFF, but LMA=0 in PE.
Now that VMA is always 0, this is no longer required (LMA=VMA=0 in both
PE and COFF).
This can be used on global directives (e.g. global _foo:function) to
indicate the global is a function. This is useful for incremental
linking in MSVC.
Changed segment:offset calculations so that vstart = 16*segment +
offset and vseg = segment instead of vstart = offset. Without this the
existing code to infer vstart addresses is not useful.
Previously a line such as "times 4 mov rax, [rel foobar]" would result
in incorrect relocations being generated.

[#211 state:resolved]
- Always create a non-global absolute symbol @feat.00 with value of 1.
- Set type field to 0x20 (function) for safeseh-declared symbols.
- Force safeseh-declared symbols into the symbol table, but don't force
them to be global.

Don't generate an additional offset for _GLOBAL_OFFSET_TABLE_ if a WRT was
specified (the NASM usage). In GAS, _GLOBAL_OFFSET_TABLE_ doesn't have a WRT
but instead has special handling.
This isn't quite *exactly* the right fix; a better fix would be to recognize
the _GLOBAL_OFFSET_TABLE_ case in the GAS parser and adjust the value
appropriately there. However, this fix seems to do the right thing in the
meantime for both GAS and NASM cases.

add new objfmt interface function init_new_section() to initialize as we
go.
This fixes several issues, primarily with debug formats that create sections.
