Eric Liu 7e5445267f Fix clang-tidy crash when a single fix is applied on multiple files.
Summary:
tooling::Replacements only holds replacements for a single file, so
this patch makes Fix a map from file paths to tooling::Replacements so that it
can be applied on multiple files.

Saleem Abdulrasool 015280211b CodeView: extract the OMF Directory Header
The DebugDirectory contains a pointer to the CodeView info structure which is a
derivative of the OMF debug directory.  The structure has evolved a bit over
time, and PDB 2.0 used a slightly different definition from PDB 7.0.  Both of
these are specific to CodeView and not COFF.  Reflect this by moving the
structure definitions into the DebugInfo/CodeView headers.  Define a generic
DebugInfo union type that can be used to pass around a reference to the
DebugInfo irrespective of the versioning.  NFC.

Rui Ueyama 776c6828a5 Do not ignore SizeOfOptionalHeader in COFF header even if PE header is not present.
Attribute SizeOfOptionalHeader is ignored if no PE header is present
in the file. This attribute should be ignored according to standard,
however there are uses of this field even though it should not be used.

This change does not conform to PE/COFF standard, but there are several
COFF files without PE header, where you had to add up SizeOfOptionalHeader
in order to get proper section headers. Other tools and their own parsers
do take this into account.

Lang Hames 33c0b6bfca [RuntimeDyld][Orc][MCJIT] Add partial weak-symbol support to RuntimeDyld.
This patch causes RuntimeDyld to check for existing definitions when it
encounters weak symbols. If a definition already exists then the new weak
definition is discarded. All symbol lookups within a "logical dylib" should now
agree on the address of any given weak symbol. This allows the JIT to better
match the behavior of the static linker for C++ code.

This support is only partial, as it does not allow strong definitions that
occur after the first weak definition (in JIT symbol lookup order) to override
the previous weak definitions. Support for this will be added in a future
patch.

Michael Kruse a6cc0d3a2d [ScopDetection] Remove unused DetectionContexts during expansion.
The function expandRegion() frees Region* objects again when it determines that
these are not valid SCoPs. However, the DetectionContext added to the
DetectionContextMap still holds a reference. The validity is checked using the
ValidRegions lookup table. When a new Region is added to that list, it might
share the same address, such that the DetectionContext contains two
Region* associations that are in ValidRegions, but that are unrelated and of
which one has already been free.

Also remove the DetectionContext when not a valid expansion.

Charles Davis 3e43970d71 [Attr] Add support for the `ms_hook_prologue` attribute.
Summary:
Based on a patch by Michael Mueller.

This attribute specifies that a function can be hooked or patched. This
mechanism was originally devised by Microsoft for hotpatching their
binaries (which they're constantly updating to stay ahead of crackers,
script kiddies, and other ne'er-do-wells on the Internet), but it's now
commonly abused by Windows programs that want to hook API functions. It
is for this reason that this attribute was added to GCC--hence the name,
`ms_hook_prologue`.

Depends on D19908.

Charles Davis 0822aa118e [X86] Support the "ms-hotpatch" attribute.
Summary:
Based on two patches by Michael Mueller.

This is a target attribute that causes a function marked with it to be
emitted as "hotpatchable". This particular mechanism was originally
devised by Microsoft for patching their binaries (which they are
constantly updating to stay ahead of crackers, script kiddies, and other
ne'er-do-wells on the Internet), but is now commonly abused by Windows
programs to hook API functions.

This mechanism is target-specific. For x86, a two-byte no-op instruction
is emitted at the function's entry point; the entry point must be
immediately preceded by 64 (32-bit) or 128 (64-bit) bytes of padding.
This padding is where the patch code is written. The two byte no-op is
then overwritten with a short jump into this code. The no-op is usually
a `movl %edi, %edi` instruction; this is used as a magic value
indicating that this is a hotpatchable function.

This patch makes them pure functions -- that has no side effect and
don't update arguments to improve readability.

Now each function construct a patial result, and all resutls are then
bitwise-OR'ed to construct the final result.

This patch also creates a new file, Mips.cpp, to move all these
MIPS functions to a separate file.
