Alan Modra fd3619828e bfd_section_* macros 
This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions.  The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections.  Those sections shouldn't be modified
anyway.

The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma.  I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section.  This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

Dimitar Dimitrov 2688aab226 Update PRU assembler to corect hardware register numbering for DWARF. 
A small rework of the PRU GCC port exposed that CIE data alignment is
erroneously set to 4 for PRU in GAS. In fact PRU stack must be aligned to 1.
Set the macro to -1, to allow output from GCC to be assembled without errors.

Also, while at it, set DWARF2 HW register numbering to follow latest

	* config/tc-pru.c (pru_regname_to_dw2regnum): Return the starting HW
	byte-register number.
	(pru_frame_initial_instructions): Use byte-numbering for FP index.
	* config/tc-pru.h (DWARF2_DEFAULT_RETURN_COLUMN): Use number from
	latest GCC.
	(DWARF2_CIE_DATA_ALIGNMENT): Set to -1.

Dimitar Dimitrov 493ffac5aa Fix binary compatibility between GCC and the TI compiler for the PRU target. 
My original implementation for LDI32 pseudo does not conform to
the TI ABI.  I wrongly documented my TI PRU ELF object files inspection,
which got propagated into my binutils implementation.

Issue was exposed when running the GCC ABI testsuite against TI toolchain.
According to TI ABI, LDI32 must use first LDI instruction to load
the MSB 16bits, and second LDI instruction for the LSB 16bits.

This patch will break binary compatibility with previously released
binutils versions for PRU. Still, I think it is better to fix
binutils to conform to the chip vendor ABI.

Dimitar Dimitrov ddb2c6fdfc Fix PRU GAS for 32-bit hosts 
The PRU GAS port I originally submitted does not build on 32bit hosts.
This patch fixes it by aligning md_number_to_chars's definition with
the global declaration in tc.h.

Here is the original bug report I got:
  https://github.com/rcn-ee/repos/pull/23#issuecomment-269915175

	* config/tc-pru.c (md_number_to_chars): Fix parameter to be
	valueT, as declared in tc.h.
	(md_apply_fix): Fix to work on 32-bit hosts.
