This is a follow-up to rL343482 / D52439.
This was a pattern that initially caused the commit to be reverted because
the transform requires a bitcast as shown here.

Summary:
This attribute allows excluding a member of a class template from being part
of an explicit template instantiation of that class template. This also makes
sure that code using such a member will not take for granted that an external
instantiation exists in another translation unit. The attribute was discussed
on cfe-dev at [1] and is primarily motivated by the removal of always_inline
in libc++ to control what's part of the ABI (see links in [1]).

The check bugprone-exception-escape should not register
if -fno-exceptions is set for the compile options. Bailing out on non-cplusplus

Flag 'AllowZeroMoveEliminationOnly' should have been a property of the PRF, and
not set at register granularity.
This change also restricts move elimination to writes that update a full
physical register. We assume that there is a strong correlation between
logical registers that allow move elimination, and how those same registers are
allocated to physical registers by the register renamer.
This is still a no functional change, because this experimental code path is
disabled for now. This is done in preparation for another patch that will add
the ability to describe how move elimination works in scheduling models.

Initializing an ompt_data_t object using the pointer union member is potentially
unsafe in 32-bit programs. This change fixes the issue

The GOT is referenced through the symbol _GLOBAL_OFFSET_TABLE_ .
The relocation added calculates the offset into the global offset table for
the entry of a symbol. In order to get the correct TargetVA I needed to
create an new relocation expression, HEXAGON_GOT. It does
Sym.getGotVA() - In.GotPlt->getVA().

Summary:
Currently queries like "ab" can match identifiers like a_yellow_bee.
The value of allowing this for exactly one segment but no more seems dubious.
It costs ~3% of overall ram (~9% of posting list ram) and some quality.

1) Instead of x$$ for a short-query trigram, just use x
2) Make rules more coherent: prefixes of length 1-2, and first char + next head
3) Fix Dex::fuzzyFind to mark results as incomplete, because
short-trigram rules only yield a subset of results.

Summary:
The FALSE iterator will be used in a followup patch to fix a logic bug in Dex
(currently, tokens that don't have posting lists in the index are simply dropped
from the query, changing semantics).
It can usually be optimized away, so added the following opmitizations:
- simplify booleans inside AND/OR
- replace effectively-empty AND/OR with booleans
- flatten nested AND/ORs
While working on this, found a bug in the AND iterator: its constructor sync()
assumes that ReachedEnd is set if applicable, but the constructor never sets it.
This crashes if a non-first iterator is nonempty.

f32 values passed on the stack would previously cause an assertion in
unpackFromMemLoc.. This would only trigger in the presence of the F extension
making f32 a legal type. Otherwise the f32 would be legalized.
This patch fixes that by keeping LocVT=f32 when a float is passed on the
stack. It also adds test coverage for this case, and tests that also
demonstrate lw/sw/flw/fsw will be selected when most profitable. i.e. there is
no unnecessary i32<->f32 conversion in registers.
