arm:thumb:compiling with  O2

The compiler was targeting -Os before this commit, now it targets -O2

No error on array-bounds

O3 flag raises an error when array subscript is above array bounds, passing Wno-array-bounds prevents the compiler to stop working when facing this error

clang: updated unsupported flags

fgcse-las, fgcse-sm and fgcse-after-reload are not supported by clang, we have to notice the compiler to ignore them

build: Handle custom boot images properly

When a pre-built image should be used, it should be stored in the
target files zip so that it can be used with external signing
processes.

ota: Let devices specify their own recovery-from-boot.p installer

Some devices apply transformations to the installed images, making
the sha1 checksums fail (or, worse, generating invalid images). If
"/system/etc/recovery-transform.sh" exists, run that instead, passing
the expected sizes and checksums as arguments in the form of

recovery-transform.sh <recovery_size> <recovery_sha1> <boot_size> <boot_sha1>

A direct emulation of the standard patcher could look like this, transformations
should be added as needed.

----------------
RECSIZE=$1
RECSHA1=$2
BOOTSIZE=$3
BOOTSHA1=$4

dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=$C/recovery.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=$C/boot.img

if ! applypatch -c EMMC:$C/recovery.img:$RECSIZE:$RECSHA1; then
  log -t recovery "Installing new recovery image"
  applypatch -b /system/etc/recovery-resource.dat EMMC:$C/boot.img:$BOOTSIZE:$BOOTSHA1 EMMC:$C/recovery.img $RECSHA1 $RECSIZE $BOOTSHA1:/system/recovery-from-boot.p || exit 1
else
  log -t recovery "Recovery image already installed"

Enabled Swing Modulo Scheduling

-fmodulo-sched and -fmodulo-sched-allow-regmoves are fairly new optimizations not currently automatically enabled at any -O level.
These options improve loop scheduling – more information can be found there: https://gcc.gnu.org/news/sms.html.
