COFF: Support exception table. .pdata section contains a list of triplets of function start address, function end address and its unwind information. Linkers have to sort section contents by function start address and set the section address to the file header (so that runtime is able to find it and do binary search.) This change seems to resolve all but one remaining test failures in check{,-clang,-lld} when building the entire stuff with clang-cl and lld-link. llvm-svn: 240231

COFF: Fix logic to find default entry name or subsystem. The previous logic to find default entry name or subsystem does not seem correct (i.e. was not compatible with MSVC linker). Previously, default entry name was inferred from CRT functions and user-defined entry functions. Subsystem was inferred from CRT functions. Default entry name and subsystem are now inferred based on the following table. Note that we no longer use CRT functions to infer them.
