Teresa Johnson bbd10b4579 [ThinLTO] Option to control path of distributed backend files
Summary:
Add support to control where files for a distributed backend (the
individual index files and optional imports files) are created.

This is invoked with a new thinlto-prefix-replace option in the gold
plugin and llvm-lto. If specified, expects a string of the form
"oldprefix:newprefix", and instead of generating these files in the
same directory path as the corresponding bitcode file, will use a path
formed by replacing the bitcode file's path prefix matching oldprefix
with newprefix.

Also add a new replace_path_prefix helper to Path.h in libSupport.

Depends on D19636.

Cameron Desrochers 6fffec3c96 [PCH] Fixed bug with preamble invalidation when overridden files change
When remapped files were changed, they would not always cause the preamble's PCH to be invalidated, because the remapped path didn't necessarily match the include path (e.g. slash direction -- this happens a lot on Windows). I fixed this by moving to a llvm::sys::fs::UniqueID-based map instead of comparing paths stringwise.

Renato Golin 57bfb69aa4 [ARM] ARM mov InstAlias for MOVW lacks HasV6T2
The movw instruction is only available in ARM state for V6T2 and above.
The MOVi16 instruction has requirement HasV6T2 but the InstAlias
for mov rd, imm where the operand is imm0_65535_expr:$imm does not.

This means that movw can incorrectly be used in ARMv4 and ARMv5 by
writing mov rd, 0x1234. The simple fix is to the requirement HasV6T2
to the InstAlias. Tests added to not-armv4.s.

Patch by Peter Smith.

Simon Dardis 8d8f2f8b8d [mips] Compact branch policy control for MIPSR6
This patch adds the commandline option -mips-compact-branches={never,optimal,always),
which controls how LLVM generates compact branches for MIPS targets. By
default, the compact branch policy is 'optimal' where LLVM will (hopefully)
pick the optimal branch for any situation. The 'never' policy will disable
the generation of compact branches and 'always' will generate compact branches
wherever possible.

Derek Schuff 1aaf87e91d Factor PrologEpilogInserter around spilling, frame finalization, and scavenging
PrologEpilogInserter has these 3 phases, which are related, but not
all of them are needed by all targets. This patch reorganizes PEI's
varous functions around those phases for more clear separation. It also
introduces a new TargetMachine hook, usesPhysRegsForPEI, which is true
for non-virtual targets. When it is true, all the phases operate as
before, and PEI requires the AllVRegsAllocated property on
MachineFunctions. Otherwise, CSR spilling and scavenging are skipped and
only prolog/epilog insertion/frame finalization is done.

Maxim Ostapenko 02c21b3ef9 [asan] Don't raise false alarm to recv/recvfrom when MSG_TRUNC is present.
Fix https://llvm.org/bugs/show_bug.cgi?id=27673.

Currenty ASan checks the return value of real recv/recvfrom to see if the written bytes fit in the buffer. That works fine most of time.
However, there is an exception: (from the RECV(2) man page)

MSG_TRUNC (since Linux 2.2)
    ... return the real length of the packet or datagram, even when it was longer than the passed buffer. ...

Some programs combine MSG_TRUNC, MSG_PEEK and a single-byte buffer to peek the incoming data size without reading (much of) them. In this case,
the return value is usually longer than what's been written and ASan raises a false alarm here. To avoid such false positive reports,
we can use min(res, len) in COMMON_INTERCEPTOR_WRITE_RANGE checks.
