Summary:
This patch implements a `BlockVerifier` type which enforces the
invariants of the log structure of FDR mode logs on a per-block basis.
This ensures that the data we encounter from an FDR mode log
semantically correct (i.e. that records follow the documented "grammar"
for FDR mode log records).

This is another part of the refactoring of D50441.

Summary:
When targeting MSVC: compile using clang's cl driver mode (this is needed for
libfuzzer's exit_on_src_pos feature). Don't use -lstdc++ when linking,
it isn't needed and causes a warning.
On Windows: Fix exit_on_src_pos.test by making sure debug info isn't
overwritten during compilation of second binary by using .exe extension.

By calling these NativeType<foo>.cpp, they will all be sorted
together, and it also distinguishes the types from the symbols.

llvm-svn: 341609

Part of the responsibility of the native PDB reader is to cache
symbols the first time they are accessed, so they can then be
looked up by an ID.  Furthermore, we need to resolve type indices
to records that we vend to the user, and other things.  Previously
this code was all thrown together a bit haphazardly in the native
session class, but it makes sense to collect all of this into a
single class whose sole responsibility is to manage the collection
of known symbols.

  Second Attempt. Alignment issues resolved. zlib::isAvailable() detected.

  Usage:

  llvm-objcopy --compress-debug-sections=zlib foo.o
  llvm-objcopy --compress-debug-sections=zlib-gnu foo.o

  In both cases the debug section contents is compressed with zlib. In the GNU
  style case the header is the "ZLIB" magic string followed by the uint64 big-
  endian decompressed size. In the non-GNU mode the header is the
  Elf(32|64)_Chdr.

  Decompression support is coming soon.

ADC is commutable and the load could be in either operand, but we were only checking operand 0.

Ideally we'd mark X86adc_flag as commutable and tablegen would automatically do this, but the EFLAGS register mention is preventing it.

llvm-svn: 341606

[X86] Add a test case showing failure to use the RMW form of ADC when the load is in operand 1 going into isel.

The ADC instruction is commutable, but we only have RMW isel patterns with a load on the left hand side. Nothing will canonicalize loads to the LHS on these ops. So we need two patterns.

interceptors for malloc/free/etc and only export their versions with
__sanitizer_ prefix.

The peephole pass likely gets this normally, but we should be doing it during isel.

SHF_ARM_PURECODE flag when being built with the -mexecute-only flag.
All code sections of an ELF must have the flag set for the final .text
section to be execute-only, otherwise the flag gets removed.

A HasData flag is added to MCSection to aid in the determination that
the section is empty. A virtual setTargetSectionFlags is added to
MCELFObjectTargetWriter to allow subclasses to set target specific
section flags to be added to sections which we then use in the ARM
backend to set SHF_ARM_PURECODE.
