[DAGCombine] Match more patterns for half word bswap
Summary: It ensures that the bswap is generated even when a part of the
subtree already matches a bswap transform.

Fix some dangling else warnings
EXPECT_EQ contains an if-else statement. It also contains some magic to
suppress the dangling else warnings, but it seems that some new
compilers can see through that...

Commit 5070322332441beb04951e22c1972f3e0113d47e by pavel
Fix the unwinding plan augmentation from x86 assembly
Unwind plan augmentation should compute the plan row at offset x from
the instruction before offset x, but currently we compute it from the
instruction at offset x. Note that this behavior is a regression
introduced when moving the x86 assembly inspection engine to its own
file
(https://github.com/llvm/llvm-project/commit/1c9858b298d79ce82c45a2954096718b39550109#diff-375a2be066db6f34bb9a71442c9b71fcL913);
the original version handled this properly by copying the previous
instruction out before advancing the instruction pointer.

Commit 819f01d917fbb89af0614e10a0a513d294c9b098 by kai.nacke
[Tests] Output of od can be lower or upper case (llvm-objcopy/yaml2obj).
The command `od -t x` is used to dump data in hex format. The LIT tests
assumes that the hex characters are in lowercase. However, there are
also platforms which use uppercase letter.
To solve this issue the tests are updated to use the new
`--ignore-case` option of FileCheck.

Commit 55f1be09967e816be49fefce45211b8f7222c044 by grimar
[llvm-readelf] - Do not enter an infinite loop when printing histogram.
This is similar to D68086. We are entering an infinite loop when dumping
a histogram for a specially crafted
.hash section with a loop in a chain.
