[PATCH][AArch64] Fix missing optimization for CMP+AND
During combine GCC tries to merge CMP (with zero) and AND into a TST. However,
in cases where an ANDS operand is not compatible, this was being missed. Adding

[rs6000] Avoid rotates of floating-point modes
The little-endian VSX code uses rotates to swap the two 64-bit halves of
128-bit scalar modes. This is fine for TImode and V1TImode, but it
isn't really valid to use RTL rotates on floating-point modes like
KFmode and TFmode, and doing that triggered an assert added by the
SVE series. This patch uses bit-casts to V1TImode instead.

x86: Properly check saved register CFA offset
X86 prologue saves register at CFA offset. Since its location on stack
is computed as CFA - its CFA_OFFSET, CFA_OFFSET points the end of the

compiler: clean up unresolved placeholders for pointer types
Add a new helper routine Type::finish_pointer_types that walks through
the pointer type cache and looks for placeholder types that may have
been created at some point before conversion of named types, and
invokes Type::finish_backend() on said placeholders. This is needed
to handle cases where the compiler manufactures a pointer type as part
of lowering, then a placeholder is created for it due to a call to
Type::backend_type_size(), but there is no explicit reference to the
type in user code.
