  checkasm: arm: report the first clobbered register in checkasm_checked_call

Also includes 446353ea18, 59aeed93e4, and 37961044c6 to avoid breaking
too much stuff.

They only contain one line and will never contain more.

a05cc56124 checkasm: arm/aarch64: Fix the amount of space reserved for stack parameters
Even if MAX_ARGS - 2 (for arm) or MAX_ARGS - 7 (for aarch64) parameters
are passed on the stack to checkasm_checked_call, we actually only
need to store MAX_ARGS - 4 (for arm) or MAX_ARGS - 8 (for aarch64)
parameters on the stack when calling the tested function.

6f9e34baea arm: Check for support for the .fpu directive
When targeting COFF (windows), clang doesn't support this
directive (while binutils supports it for all targets).

37961044c6 checkasm: arm: Ignore changes to bits 0-4 and 7 of FPSCR
These bits are set by exceptions in NEON instructions.

Also print the differing bits when FPSCR is clobbered,
and use bic instead of lsl, for clearing the topmost bits.

59aeed93e4 cheackasm/arm: remove NEON instructions from checkasm_checked_call_vfp
Fixes AS error on non NEON builds introduced in 71a0472114. Also
set the fpu directly to vfp in checkasm.S to cause build errors on NEON
builds.

446353ea18 checkasm: arm: Don't start new const blocks for each string
Each const block needs to be terminated by one endconst
invocation so either call endconst after each, or just
declare plain labels to the later strings.

This fixes errors such as this, on some binutils versions:

checkasm.S:38: Error: Macro `endconst' was already defined

7b1ae0e73a checkasm/arm: preserve the stack alignment checkasm_checked_call
The stack used by checkasm_checked_call_vfp was a multiple of 4 when the
checked function is called. AAPCS requires a double word (8 byte)
aligned stack public interfaces. Since both calls are public interfaces
the stack is misaligned when the checked is called.

Might fix the SIGBUS error in the armv7-linux-clang-3.7 fate config.

26ec75aec3 checkasm: Check register clobbering on arm
Use two separate functions, depending on whether VFP/NEON is available.

This is set to require armv5te - it uses blx, which is only available
since armv5t, but we don't have a separate configure item for that.
(It also uses ldrd, which requires armv5te, but this could be avoided
if necessary.)
