This commit extract the code that parses the 64-bit offset from the method
'parseOperandsOffset' to a new method 'parseOffset' so that we can reuse it
when parsing the offset for the machine memory operands.

Summary: llvm::ConstantFoldTerminator function can convert SwitchInst with single case (and default) to a conditional BranchInst. This patch adds support to preserve make.implicit metadata on this conversion.

This patch fixes the sse2/avx2 vector shift by constant instcombine call to correctly deal with the fact that the shift amount is formed from the entire lower 64-bit and not just the lowest element as it currently assumes.
e.g.
%1 = tail call <4 x i32> @llvm.x86.sse2.psrl.d(<4 x i32> %v, <4 x i32> <i32 15, i32 15, i32 15, i32 15>)
In this case, (V)PSRLD doesn't perform a lshr by 15 but in fact attempts to shift by 64424509455 ((15 << 32) | 15) - giving a zero result.
In addition, this review also recognizes shift-by-zero from a ConstantAggregateZero type (PR23821).

PrettyStackTraceHead is a LLVM_THREAD_LOCAL, which means it's just a global
in LLVM_ENABLE_THREADS=NO builds. If a CrashRecoveryContext is used with
code that uses PrettyStackEntries, and a crash happens, PrettyStackTraceHead is
currently not reset to its pre-crash value. These functions make it possible
to add a cleanup to such code that does this.
(Not reseting the value then causes the assert in ~PrettyStackTraceEntry() to
fire if the code outside of the CrashRecoveryContext also uses
PrettyStackEntries -- for example, clang when building a module.)
Part of PR11974.

build so check and turn on -Wmissing-field-initializers. While there,
reorganize the conditional warning code based on compiler to be a bit
more obvious and inside a switch statement.

In tree they are only used by llvm-readobj, but it is also used by
https://github.com/mono/CppSharp.
While at it, add some missing error checking.

llvm-dsymutil has to be able to process debug info produced by other compilers
which use different line table settings. The testcase wasn't generated by
another compiler, but by a modified clang.
llvm-svn: 244319
NFC patch for current users, but llvm-dsymutil will use the new
functionality to adapt to the input linetable.
Based on a patch by Adrian Prantl.

This test was in an infinite loop in AArch64. We're investigating it
on PR24389, but I'm disabling it for now, so that we continue testing
everything else.

Summary:
Port the ReconstructShuffle function from AArch64 to ARM
to handle mismatched incoming types in the BUILD_VECTOR
node.
This fixes an outstanding FIXME in the ReconstructShuffle
code.

This change :
- Fixes offsets of all register sets for Mips.
- Adds MSA register set and FRE=1 mode support for FP register set.
- Separates lldb register numbers and register infos of freebsd/mips64 from linux/mips64.
- Re-orders the register numbers of all kinds for mips to be consistent with freebsd order of register numbers.
- Eliminates ENABLE_128_BIT_SUPPORT and union ValueData from Scalar.cpp and uses llvm::APInt and llvm::APFloat for all integer and floating point types.

... and add aarch32 to specifically refer to the 32-bit ones.
Previously, 'arm' meant only 32-bit architectures and there was no way
for a module to build with both 32 and 64 bit ARM architectures.
Now a module that is intended to work on both architectures can specify
requires arm
whereas a module only for 32-bit platforms can say
requires aarch32
and just like before, 64-bit only can say
requires aarch64
