Instead, make a local copy with appropriate addrspacecasts and let

This allows loading value of the argument using [symbol+offset]
instead of converting argument to general space pointer and using it
for indexing (which also implicitly converts param space pointer to
local space one on SASS level and triggers copying of argument into

[codeview] Add support for splitting field list records over 64KB
The basic structure is that once a list record goes over 64K, the last
subrecord of the list is an LF_INDEX record that refers to the next
record. Because the type record graph must be toplogically sorted, this
means we have to emit them in reverse order. We build the type record in
order of declaration, so this means that if we don't want extra copies,
we need to detect when we were about to split a record, and leave space
for a continuation subrecord that will point to the eventual split
top-level record.
Also adds dumping support for these records.
Next we should make sure that large method overload lists work properly.

[StackProtector] Fix computation of GSCookieOffset and EHCookieOffset with SEH4
Summary:
Fix the computation of the offsets present in the scopetable when using the
SEH (__except_handler4).
This patch added an intrinsic to track the position of the allocation on the
stack of the EHGuard. This position is needed when producing the ScopeTable.
```
struct _EH4_SCOPETABLE {
DWORD GSCookieOffset;
DWORD GSCookieXOROffset;
DWORD EHCookieOffset;
DWORD EHCookieXOROffset;
_EH4_SCOPETABLE_RECORD ScopeRecord[1];
};
struct _EH4_SCOPETABLE_RECORD {
DWORD EnclosingLevel;
long (*FilterFunc)();
union {
void (*HandlerAddress)();
void (*FinallyFunc)();
};
};
```
The code to generate the EHCookie is added in `X86WinEHState.cpp`.
Which is adding these instructions when using SEH4.
```
Lfunc_begin0:
# BB#0: # %entry
pushl %ebp
movl %esp, %ebp
pushl %ebx
pushl %edi
pushl %esi
subl $28, %esp
movl %ebp, %eax <<-- Loading FramePtr
movl %esp, -36(%ebp)
movl $-2, -16(%ebp)
movl $L__ehtable$use_except_handler4_ssp, %ecx
xorl ___security_cookie, %ecx
movl %ecx, -20(%ebp)
xorl ___security_cookie, %eax <<-- XOR FramePtr and Cookie
movl %eax, -40(%ebp) <<-- Storing EHGuard
leal -28(%ebp), %eax
movl $__except_handler4, -24(%ebp)
movl %fs:0, %ecx
movl %ecx, -28(%ebp)
movl %eax, %fs:0
movl $0, -16(%ebp)
calll _may_throw_or_crash
LBB1_1: # %cont
movl -28(%ebp), %eax
movl %eax, %fs:0
addl $28, %esp
popl %esi
popl %edi
popl %ebx
popl %ebp
retl
```
And the corresponding offset is computed:
```
Luse_except_handler4_ssp$parent_frame_offset = -36
.p2align 2
L__ehtable$use_except_handler4_ssp:
.long -2 # GSCookieOffset
.long 0 # GSCookieXOROffset
.long -40 # EHCookieOffset <<----
.long 0 # EHCookieXOROffset
.long -2 # ToState
.long _catchall_filt # FilterFunction
.long LBB1_2 # ExceptionHandler
```
Clang is not yet producing function using SEH4, but it's a work in progress.
This patch is a step toward having a valid implementation of SEH4.
Unfortunately, it is not yet fully working. The EH registration block is not
allocated at the right offset on the stack.

for Cortex-A72/Cortex-A73 before r271555 (since it was checking the CPU
string). Because Cortex-A72/Cortex-A73 inherit all features from Cortex-A57,
all decisions previously guarded by isCortexA57() are now taken.
This change restores the behaviour before r271555 by adding separate
ProcA72/ProcA73, which have the required features to preserve code
generation.

This patch makes us perform interprocedural analysis on functions that
don't have internal linkage. It also removes a test that should've been
deleted in an earlier commit (since other tests now cover everything
that the newly-removed test covers).

Add support for Darwin’s 64-bit universal files with 64-bit offsets and sizes for the objects.
Darwin added support in its Xcode 8.0 tools (released in the beta) for universal
files where offsets and sizes for the objects are 64-bits to allow support for
objects contained in universal files to be larger then 4gb. The change is very
straight forward. There is a new magic number that differs by one bit, much
like the 64-bit Mach-O files. Then there is a new structure that follow the
fat_header that has the same layout but with the offset and size fields using
64-bit values instead of 32-bit values.

Fix a relatively nasty bug with fs::getPathFromOpenFD() on Windows. The GetFinalPathNameByHandle API does not behave as documented; if given a buffer that has enough space for the path but not the null terminator, the call will return the number of characters required *without* the null terminator (despite being documented otherwise) and it will not set GetLastError(). The result was that this function would return a bogus path and no error. Instead, ensure there is sufficient space for a null terminator (we already strip it off manually for compatibility with older versions of Windows).

Fix for PR27940
After a store has been eliminated, when making sure that the
instruction iterator points to a valid instruction, dbg intrinsics are
now ignored as a new instruction.

[codeview] Add an extra check for TPI hash values.
This patch adds a function that corresponds to `fUDTAnon`
and use that to compute TPI hash values as the reference does.

Fix dynamically linked debug builds.
On the surface, this might not look like it does anything... but
actually it brings in the declaration "extern template class
AnalysisManager<Loop>;", which suppresses the instantiation of the
constructor, which avoids the funny interaction between "extern
template" and -fvisibility-inlines-hidden.
