Do previous differently by pushing even number of registers and remove
strange r7 usage.

Align sp to 8-byte boundary as required by EABI.

This is especially important for non-leaf functions; GCC optimizes codes
based on assumption that sp is aligned properly.

Mostly fix broken earmv5 u

Align sp to 8-byte boundary as required by EABI.

This is especially important for non-leaf functions; GCC optimizes codes
based on assumption that sp is aligned properly.

Mostly fix broken earmv5 userland compiled by GCC10 due to alignment
faults in ld.elf_so, where {ld,st}rd are used for [sp, #8x].

No regression for ATF is observed for earmv[67]{,hf}{,eb}.

Import compiler-rt r259194. Primary changes are better support for
128bit long double and a number of refinements in the profiling backend.

Import compiler-rt r215309. Extends 128bit IEEE support in soft-float,
uses Thumb mode by default on ARM when available and fixes a bug in the
division code for ARMs with hardware integer division.

Import compiler-rt r208593. Fix a build bug in __clear_cache by not
explicitly forcing the ABI. Add first part of IEEE 754 quad support.

Import compiler-rt r202303. Extend 128bit support to all LP64 platforms.
